Question

Find area of a circle that has a diameter of 8 m

Answer 1

50.24 m^2

Explanation:

Area of a circle = Pi r^2

Pi = 3.14

Diameter = 8 m

Radius r = diameter/2 = 8/2

= 4

Therefore

Area = 3.14 x 4^2

= 3.14 x 4 x 4

= 50.24 m^2

Answer 2

Diameter \ 2 = radius
8/2 = 4
4^2 = 16
16*pi is about 50.27
Your area is 50.27m^2
