Answer:
64 pi
Explanation:
Area of circle = Pi X R^2
Diameter is double the radius so you have it.
16/2 = 8
Pi X 8^2
8^2 = 64
64 Pi
(In terms of pi simply means work out the answer and add pi to the end)
Answer: A≈201.06
To find the area of a circle with the radius, square the radius, or multiply it by itself. Then, multiply the squared radius by pi, or 3.14, to get the area. To find the area with the diameter, simply divide the diameter by 2, plug it into the radius formula, and solve as before.
