A circular pan has a diameter of 8 inches. What is the exact area of the pan?

A.

256π square inches

B.

8π square inches

C.

64π square inches

D.

16π square inches

You would divide the diameter in half to get the radius which is 4. And do the formula which is a=pie (r) squared. So the answer would be 50.24

Diameter of a circle = 2r

an area of a circle = πr²

so, if the diameter of the circular pan is 8 inches taht menas,

2r = 8

or, r = 4 inches

so area of the pan = πr² = 22/7 * 4 = 12.57 inches
