Question

IF DIAMETER OF A CIRCLE IS 28 CM FIND ITS RADIUS AND CIRCUMFERENCE

Answer 1

To find the area first we need to find the radius of the circle from the diameter.

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

Answer 2

Answer:

r= 28/2= 14cm

circumference= 2pir

2 x 22/7x 14

2 x 22 x 2= 88cm^2
