Answer:
176.7 in²
Step-by-step explanation:
The formula for the area of a circle is πr².
But first, you have to find the radius. The radius is half of the diameter, which is the length from one edge of the circle to the other.
Here the diameter is 15 in. Divide the diameter by 2 to get the radius.
r = 15 ÷ 2 = 7.5 in
Now plug the radius into the formula and solve for the area.
A = πr²
A = π(7.5)²
A = π(56.25)
A = 176.7145868 ⇒ 176.7 in²
Hope that helps.
