Question

the radius of a circle is 10 feet. what is the area? r = 10 ft give the exact answer in simplest form. square feet

Explanation:

Step1: Recall area formula

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

Step2: Substitute radius value

Given $r = 10$ ft, substitute into the formula: $A=\pi\times(10)^{2}$.

Step3: Calculate result

$(10)^{2}=100$, so $A = 100\pi$ square - feet.

Answer:

$100\pi$
