A circle and a square have equal perimeters (the circle's circumference equals the square's perimeter). The square has side 11 cm. Find the area of the circle. (Take π = 22/7)

Question

Accepted Answer

154 cm^2. Square perimeter = 4*11 = 44 cm. So 2*π*r = 44 gives r = 44 × 7/2 × 22 = 7 cm. Circle area = 22/7*7*7 = 154 cm^2.

A circle and a square have equal perimeters (the circle's circumference equals the square's perimeter).
