If the circumference of a circle is 352 cm then find the area of the circle?
Let the radius of a circle = (r) cm Circumference of circle = 2πr According to the question ⇒ 2 x π x r = 352 ⇒ 2 x (22/7) x r = 352 ⇒ r = (352 x 7)/(22 x 2) ⇒ r = 56 cm Area of circle = πr2 Area of circle = 22/7 x 56 x 56 Area of circle = 9856 cm2
