Sheldon cuts a circle with a diameter of 14 centimeters from a square piece of felt 15 inches on each side. In terms of pi, how much felt is left over? Show Work
The entire area of the felt is 15 x 15 = 225 square inches The circle cut from the felt = circle area = PI * radius^2 circle area = PI * 7^2 circle area = 49 * PI 49 * PI =
153.94 Left over felt 225 -153.94 = 71.06
15 x 15 = 225 square inches The circle cut from the felt = PI * radius^2 = PI * 7^2 = 49 * PI 49 * PI = 153.94 225 -153.94 = 71.06 71.06 felt is left over
