Question

The figure below is composed of a rectangle and two quarter circles. What is the area of the figure?

A) 132.97 cm^2
B) 94.48 cm^2
C) 75.24 cm^2
D) 209.94 cm^2

Answer 1

A) 132.97 cm²

Explanation:

first, find the area of the rectangle.

8×7=56

then, find the area of the two quarter circles (ill just calculate for a half circle since bith quarters are the same)

the radius is 7, qnd the formula for a half circle is 1/2(πr2 )

so just plug in and solve

1/2(×7²)

π×7² is 153.86

153.86/2 is 76.93

then add those two areas together

76.93+56 = 132.96 (i used 3.14 for pi, but im assuming this calls for the actual pi to be used, so just round to 132.97)
