Verified Answer :

we are given the diameter of the circle, I assume. In this case, the formula of the area of the circle is expressed as A = pi d^2/4. where pi is a constant. The only option taht makes sense here is C. 6.25 in2. This should have the constant pi on it.

we know that

the area of the circle is equal to

\(A=\pi r^{2}\)

where

r is the radius of the circle

In this problem we have

\(Diameter=5\ in\\r=Diameter/2\\r=5/2\\r=2.5\ in\)

substitute the value of r in the area's formula

\(A=\pi*2.5^{2}\)

\(A=6.25\pi\ in^{2}\)

therefore

the answer is

\(6.25\pi\ in^{2}\)
