Answer: D. 61 in²
Step-by-step explanation:
This problem is asking for us to solve the area of the given circle. We will use the formula and solve.
Please note that the formula asks for the radius and 9 in is the diameter. Since the radius is half the diameter, we will divide 9 in by 2 for a radius of 4.5 in.
A = πr²
A = π(4.5 in)²
A ≈ 63.62 in²
The closest option they give to solve this problem is D. 61 in²
About 61 in² of pie crust is needed to cover the top of the pie.
