Question

Find the circumference and area of a circle with a diameter of 22 inches. Leave your answers in terms of pi.

C = 11π; A = 44π

C = 22π; A = 44π

C = 11π; A = 121π

C = 22π; A = 121π

Answer 1

Area = pi x radius^2
Circumference = 2 x pi x radius

Diameter = 2 x radius

Answer 2

Since you know the diameter, you can find the radius. Then you just plug the radius into the other two equations, and voila!

Answer 3

C = 22π; A = 121π
