Question

difference between the circumference and diameter of a circle is 28cm. find the radius

Answer 1

Diameter = 28 cm

Radius = diameter/2

          = 28/2

          = 14 cm

Area of circle = Π r ²

                   =  ( 22/7 )  x (14)²

                   = ( 22/7 )  x 14 x 14

                   = 22 x 2 x 14

                   = 44 x 14

                   = 616 cm²
