Question

Jan is trying to fix her circular window and needs to know how much space it takes up. It has a diameter of 10 inches.

Answer 1

ANSWER

The area is 78.54 in²

EXPLANATION

We need to find the area of this circle. The area of a circle with radius r is:

$A=\pi r^2$

The diameter of a circle is twice the radius, so if the diameter is 10 inches, then the radius is 5 inches:

$A=\pi\cdot5^2=25\pi=78.54in^2$

This answer is rounded to the nearest hundredth.
