Answer:
47.1

A=PIEr^2
if you have the diameter you dont need to square it so it is simply PIE(15)
then you get 47.1238898
round it
47.1
Answer:
176.6 mm^2
Step-by-step explanation:
We need to find the radius
r = d/2
r = 15/2 = 7.5
We want the area of a circle
A = pi r^2
A = pi * (7.5)^2
= 3.14 * 56.25
=176.625
Rounding to the nearest tenth
176.6 mm^2
