What is the area of a circle with circumference 88 cm ?
616 sq cm
546 sq cm
600 sq cm
615 sq cm
Circumference = 2 * pi * r = 88. r = 88 / (2 * 22/7) = 14. Area = pi * r^2 = 22/7 * 14 * 14 = 22 * 28 = 616.
The radius equals the circumference divided by 2 pi, so 88 divided by 44 divided by 7 gives 14 cm. The area is pi times the square of the radius, so 22 divided by 7 times 14 times 14 equals 616 square cm.
