Question

Calculate the area of the shaded region

Answer 1

75.36

Explanation:

the first step is to find the area of the circle

area is pi x radius^2

3.14 times 64 is ~ 200.96

the next step is to set up a porportion.

135/360 =x/200.96

cross multiply

135 times 200.96 =27129.6

the divide that by 360

x is 75.36

Answer 2

24π ≈ 75.36

Explanation:

First find the area of the circle given the radius

πr² = π (8²) = 64π

The shaded region of the circle to the entire area of the circle is 3/8

Therefore multiply 64π by 3/8 to get your answer

This gives you 24π
