#### Answer

C = 12$\pi$ $\approx$37.7 yd
A = 36$\pi$ $yd^{2}$ $\approx$ 113.1 $yd^{2}$

#### Work Step by Step

Given d = 12 yd
Formula for circumference of a circle: C = $\pi$d = $\pi$ x 12 = 12$\pi$ = 37.7 yd
Formula for Area of a circle: A = $\pi$ $r^{2}$
=$\pi$ $6^{2}$
= 36$\pi$ $yd^{2}$
=113.1 $yd^{2}$
