Making generalizations and What is a solid figure? abstraction about the - Solid figures have three dimensions the length, lesson width and the height. Solids are boundaries that enclose a part of space. There are two kinds, the prism and pyramid. What is a prism? A pyramid? - A prism is a solid figure whose two bases are congruent polygon in parallel planes, and the other faces called lateral faces, are parallelograms. - A pyramid is a space figure in which one face is called the base, and the other faces, called lateral faces, are triangles having a common vertex called the apex. I. Evaluating There are solid figures that are bounded by curve surfaces. - A cylinder is a prism with bases bounded by simple closed curves usually circles. - A cone is a pyramid with circular base and all line segments from a circle meet at a point called apex.

If we let x be the unknown number, how can these sentence be translated into mathematical equations? What is the value of x? The first sentence can be translated to mathematical equation as: increased by 5 is 12 D. Discussing New Concepts and Practicing New Skills #1 Solving the equation, we have: x+5 =12 x + 5 – 5 = 12 – 5 Subtract 5 from both sides. x+0 =7 x= 7 To check the solution, substitute 7 for x in the equation. x + 5 = 12 7 + 5 = 12 12 = 12 The second sentence can be translated to mathematical equation as: Let x be the second number. Since, the first number is 3, then, the equation is 3 + x = 8 Solving the equation, we have: 3+x=8 3–3+x=8–3 Subtract 3 from both sides. 0+x=5 x=5 To check the solution, substitute 5 for x in the equation. 3+x =8 3+5=8 8=8 Study these other examples of finding solution to equations: 1. Find the solution to variable x in the equation, x + 5 = 20. x + 5 = 20 transpose 5 to the other side of the equation using the inverse operation x = 20 – 5 x = 15 To check, evaluate x + 5, given x = 15 x + 5 = 15 + 5 = 20 the result is 20, therefore 15 is the value of x in x + 5 = 20. 157 E.

Why is it important to follow the steps in solving problems? Read and solve the problem: A basket is full of fruits with avocado and orange. The avocado are 4 times the number of orange. 160 D. Discussing New Concepts and Practicing New Skills #1 How many of each kind of fruits are there, if there are 50 fruits in the basket? n = number of orange The avocado are 4x the number of orange, so if n is number of orange; the number of avocado is 4n. 4n = number of avocado Add the number of orange and avocado and we will have the total number of fruits. Since the total number of fruits is 50 , therefore, the equation will be: 4n + n = 50 Discussion: Try to look at how expressions are simplified. If we give a value to the variable, we can evaluate an algebraic expressions. Let’s evaluate 5a + 4b, if a =3 and b =5. 5a means 5 times a and we write: 5*a or 5 (a) 4b means 4 times b and we write: 4*b or 4 (b) To evaluate 5a + 4 b, given a=3 and b=5, we may do this: 5a + 4b = 5 (3) + 4 (5) = 15 + 20 = 35 Notice that we get a number when we evaluate an expression. We also need to follow the rule of operations. That is, starting from left to right, multiply or divide first before adding or subtracting. E.

How do you find the area of this covered court? Is it possible to find the area? 1. The pupils will present their output after 10 minutes. 2. The teacher will check their answer. D. Discussing new concepts and practicing new skills # 1 To find the area of composite figures, you can sometimes separate it into figures with areas you know how to find. Show example: Find the area of each shaded region. Assume that all angles that appear to be right angles are right angles. 6 cm a. 7 cm We can separate the figures into two: a triangle and a square. Now let us find the area of each figure. Solution: Area of the triangle A= 1 • b • h 2 6 cm Area of the square A=s•s = 7 cm • 7 cm = 1 • 7 cm • 6 cm 2 = 1 • 42 cm² 2 A = 21 cm² 225 = 49 cm² 7 cm We can see that the area of 49 cm² + = 21 cm Therefore, the area of the composite figure is 70 cm² 3 ft b. 6 ft 3 ft 3 ft 3 ft 6 ft 4ft 10 ft We can identify two rectangles from the figure, one that measures 3 feet by 4 feet (the smaller) and the 10 feet by 6 feet rectangle (the larger) where the smaller one overlapped. Let us solve the area of each rectangle. Area of the smaller rectangle A=l•w 4 ft = 4 ft • 3 ft 3 ft A (smaller) = 12 ft² Area of the larger rectangle A=l•w = 10 ft • 6 ft 6 ft A (larger) = 60 ft² 10 ft To get the area of the shaded region, subtract the area of the smaller rectangle from the area of the larger rectangle. 226 A (shaded) = A (larger) - A (smaller) = 60 ft² - 12 ft² = 48 ft² The area of the shaded region is 48 ft² E.

The area of a circle is 3.14 times the radius squared (πr2). Now, you will need to find the area of the cone itself. In order to do this, you must measure the side (slant height) of the cone. Make sure you use the same form of measurement as the radius. You can now use the measurement of the side to find the area of the cone. The formula for the area of a cone is 3.14 times the radius times the side (πrl). So the surface area of the cone equals the area of the circle plus the area of the cone and the final formula is given by: SA = πr2 + πrl How do we find the surface area of a cone? To find the surface area of a sphere, use the formula (4πr2), where r = the radius of the circle How do we find the surface area of a pyramid? To find the surface area of a pyramid, we need to find the lateral area (L.A.) and the area of the base (B), then add: S.A. = L.A. + B. Write the formula then solve. 1.Find the surface area of the ice cream cone with a radius of 2 cm and slant height of 6 cm. 2.Calculate the surface area of a basketball with a radius of 4 decimeters. 3.Compute for the surface area of a tent with a rectangular base that measures 3 meters wide and 4 meters long; and a height of 2 meters. 255 J.
