Question

Area of a rectangle and area of a circle are equal. if the dimensions of the rectangle are 14 cm X 11 cm , then find the radius of the circle.

Answer 1

$area \: of \: rectangle\: = 11 \times 14 = 154 \\ since \: area \: of \: rectangle \: = area \: of \: circle \\ so \: area \: of \: circle = \pi {r }^{2} \\154 =22 \div 7 \times {r}^{2} \\ 154 \times 7 \div 22 = {r }^{2} \\ 49 = {r}^{2} \\ \sqrt{49} = r \\ r = 7$
