Find the areas of the circle, if diameter=16cm

Reika [66]

Hey there!

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

Formula for the radius of a circle: $r = d/2\\$

First, let's divide the diameter by 2 in order to find the radius.

16/2 = 8

Next, we'll plug our values into the formula (found above).

A = pi x 8^2

A = pi x 64

A = 64pi^2 or A = 201.1cm^2

Hope this helps!! :)
