The diameter of Z is 5 in. What is its area in terms of pi?

A. 2.5in. 2

B. 5in. 2

C. 6.25in. 2

D. 25in. 2

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.
