Question

the radius of a circle is 8 inches. what is the circles area?
round your answer to the nearest hundredth.
____ square inches

Explanation:

Step1: Recall circle area formula

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

Step2: Substitute radius value

Substitute $r = 8$ inches into the formula:
$A = \pi (8)^2$

Step3: Calculate squared radius

Compute $8^2$:
$8^2 = 64$
So, $A = 64\pi$

Step4: Compute numerical value

Use $\pi \approx 3.14159$:
$A \approx 64 \times 3.14159 = 201.06176$

Step5: Round to nearest hundredth

Round $201.06176$ to two decimal places:
$A \approx 201.06$

Answer:

201.06 square inches
