The radius of a circle is 13 ft. Find its area in terms of pi.

Answer:

The area of the circle would be 530.93 sq ft.

Step-by-step explanation:

The formula is A = π r². We know that the radius or r is 13, meaning that the new equation is A = π 13². 13 to the second power is 169 meaning that the formula would now be A = π(169). 169 times π is 590.93 getting you your answer. I hope this helped! :)

A=169pi

A=pi radius squared
A=(13x13)pi
A=169pi
The question asked to answer in the terms of pi, so you leave pi in the answer, don’t multiply it.
