find the circumference and area of the circle pictured above. c = select an answer a = select an answer question help: message instructor submit question

Explanation:

Step1: Recall the formula for circumference

The formula for the circumference of a circle is $C = 2\pi r$, where $r$ is the radius. Given $r = 11$ yd.
$C=2\pi\times11$

Step2: Calculate the circumference

$C = 22\pi$ yd. If we take $\pi\approx3.14$, then $C\approx22\times3.14 = 69.08$ yd.

Step3: Recall the formula for area

The formula for the area of a circle is $A=\pi r^{2}$, with $r = 11$ yd.
$A=\pi\times11^{2}$

Step4: Calculate the area

$A = 121\pi$ square - yards. If we take $\pi\approx3.14$, then $A\approx121\times3.14=379.94$ square - yards.

Answer:

$C = 22\pi$ yd (or approximately $69.08$ yd), $A = 121\pi$ yd² (or approximately $379.94$ yd²)
