A circle has a radius of 5 centimeters. What is the area?

schepotkina [342]

Answer:

$25\pi$

Step-by-step explanation:

The formula for the area of a circle is $A=\pi r^{2}$ , r is your radius, A is your area, and π is pi (3.1415...). You plug in your radius, or 5 into r, square it, 25, and multiply it by pi. You may be asked to use a certain number of digits of pi, and in that case you multiply for example 3.14 by 25, however $25\pi$ is the exact answer.
