Question

The diameter of a round dinner plate is 10 inches. what is the area of the plate

Answer 1

To find the area of a circle you have to do πr^2, do you will get 3.14×(5^2), and you will get 78.5

Answer 2

78.5 inches, the area equation for a circle is pi times radius squared so to find it you would take 3.14*5^2 (radius is half the diameter) so it would be 3.14*25 which equals 78.5
