What is the area of a semi-circle with a diameter of 6cm?
ANEK [815]

Formula for the area of a circle: A = pi * r^2

A semi-circle is half of a circle. So, we will need to divide the area of the total circle by 2 to find the area of a semi-circle.

r = d / 2

r = 6 / 2 = 3

A = pi * 9

A = 9pi

Semi-circle:

A = 9pi / 2

A = 4.5 pi cm^2 or 14.14 cm^2

Hope this helps!! :)
