Math help needed


Recommended Posts

We're doing circles and ran into a little bit of trouble with a couple of the problems. We need to find the area of a circle with a diameter of 6 1/2 , one with a diameter of 4 1/4 and one with the diameter of 14 3/4. Thanks


area of a circle is pi times radius_squared, or pi/4 times diameter_squared

Just put the number of the diameter in.
