Question

I have tried a good 7 practice problems but for some reason I just can’t understand it, I need help. The end answer is a fraction times pi (NOT 3.14)

Answer 1

Answer:

1/2 pi

Step by step explanation:

Find the circumference

2πr = 2xπx2 = 4π

Find the angle of JHI

Since 1/2π is 1/8 of 4π,

Angle JHI should also be 1/8 of 360 = 45 degrees

To find area, 45/360 x π X 2^2

= 1/8 x 4π

= 1/2 π
