Question

the radius of a circle is 13 meters. what is the circles area?
round your answer to the nearest hundredth.
□ square meters

Explanation:

Step1: Recall circle area formula

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

Step2: Substitute radius value

Substitute $r = 13$ into the formula:
$A = \pi \times 13^2$

Step3: Calculate squared radius

Compute $13^2 = 169$, so:
$A = 169\pi$

Step4: Compute decimal value and round

Calculate $169 \times 3.14159265 \approx 530.929158$; round to the nearest hundredth.

Answer:

530.93 square meters
