**Ms. Sue**, Friday, October 12, 2007 at 9:02pm1. The area of a circle is found by multiplying pi times the radius squared.

A = pi * r^2

In a circle with a diameter of 5.1 cm, the radius is 2.55 cm.

A = 3.14 * 6.5025

A = ??

2. The area of a triangle is found by multiplying 1/2 the base times the height.

A = 1/2 * 13 * 6

A = ??
