Answer:

A = 36π yd² ≈ 113.04 yd²

C = 12π yd ≈ 37.68 yd

Explanation:

The formula of an area of a circle:


A=\pi r^2

The formula of a circumference of a circle:


C=2\pi r

r - radius

We have r = 6yd.

Substitute:


A=\pi(6^2)=36\pi\ yd^2


C=2\pi(6)=12\pi\ yd

If you want round the answers, then use π ≈ 3.14


A\approx(36)(3.14)=113.04\ yd^2


C\approx(12)(3.14)=37.68\ yd
