Answer:


25\pi

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.
