Answer:

Area is 16 pi or about 50.27

Perimeter/circumference is 8 pi or about 25.13

Perimeter of a circle is basically the circumference. the formula of the circumference is 2 pi r. 2r = diameter

that means the circumference is 8pi or about 25.13

The formula for the area of a circle is pi r^2

The radius, or r is half the diameter. so 8/2 = 4 . The radius is 4

pi * 4^2

4^2 = 16

16 pi is the area or about 50.27
