ANSWER

The area is 78.54 in²

Step-by-step 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.
