Question

C.) Using the area formulas find the missing information 6. The circumference ofa circle is 50? feet, what is the radius ofthe circle? 7. A parallelogram has an area of 60 yd', and its height is 4 yards. What is the base? 8. A triangle has an area of 32 f, and its base is 8 feet. What is the height of the triangle? A square has a perimeter of 40 inches. What is the area of the square? 10. A trapezoid has an area of 72 in2. Its bases are 10 inches and 14 inches. What is the height of the trapezoid? 11. A trapezoid has an area of 75 mm2. One of its bases is 8mm, and its height is 5 mm. What is the other base of the trapezoid?

Explanation / Answer

Answer to the question is as follows:

6. Circumference = 2*pi*r =50pi

r = 25

7. Parallelogram = bh = 4b = 60, b =15

8. (1/2)*h*b = 32

as, b=8, we have (1/2)*b*h = 32, hence, h = 8

9. Square perimeter = 4a = 40

a=10

10. trapezoid height = h

h*(10+14)/2 = 72

h = 6

11. 5*(b+8)/2 = 75

b=22
