Question

HELP PLEASE !!! Will award MEDAL and FAN! Picture attached below.

Answer 1

Solve this using proportions. Fist calculate the area of the circle. A=pi*r^2

So the area of this circle is 46.24 pi

Since a full circle is 2pi, set pi/8 over 2pi. Which looks like this:

(pi/8)/2pi or pi/8*2pi or 1/16

Set the area of the sector over the area of the circle. Which looks like this:

area sector/ 46.24 pi

So the proportion looks like this.

area sector/46.24 pi = 1/16 = 2.89 pi rounding to the nearest tenth we get 2.9 pi
