Question

the radius of a circle is 11 miles. what is the circles area?
round your answer to the nearest hundredth.
_______ square miles

Explanation:

Step1: Recall circle area formula

The area $A$ of a circle is $A = \pi r^2$, where $r$ is the radius.

Step2: Substitute radius value

Substitute $r = 11$:
$A = \pi \times 11^2$
$A = \pi \times 121$

Step3: Calculate and round result

Compute the value: $A \approx 3.1416 \times 121 \approx 379.94$

Answer:

379.94 square miles
