Question

Find the area and the circumference of the circle with the radius 6yd.

Answer 1

Answer:

A = 36π yd² ≈ 113.04 yd²

C = 12π yd ≈ 37.68 yd

Step-by-step 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

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

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