A cake has a circumference of 25 1/7 inches. What is the area of the cake? Use 22/7 to approximate pi. Round to the nearest hund redth
1 answer:
If circumference = (2 * PI * radius) then we solve for radius radius = circumference / (2 * PI)radius = 25.142758 / 22/7 * 2radius = <span><span>4.00

circle area = PI * radius^2circle area = 22/7 * 4^2circle area = 22/7 *16
<span><span><span>circle area = 50.29 square inches </span></span></span> <span><span><span>
