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
