Answer:


176.7 in^(2)

Explanation:

The area of a circle is defined as:


A = \pi r^(2)

Where r is the radius and A is the area. We're given the diameter, 15 inches. The radius is half of the diameter, so the radius is therefore 7.5 inches. Now let's take this value back into the formula above:


A = \pi r^(2) =\pi (7.5)^(2) = 56.25\pi = 176.7 in^(2)

So the circle has an area of
176.7 in^(2)

Hope this helps!
