Answer:

Radius = 14 cm, Circumference = 88 cm

Step-by-step explanation:

d = 28 cm

r = 1 / 2 * 28

 = 14 cm

Circumference = 2πr

                         = 2 * 22 / 7 *  14

                         = 2 * 22 * 2

                         = 88 cm

Hope it helps :)

Step-by-step explanation:

Diameter (d) = 28 cm

Radius (R) = d /2 = 28 / 2 = 14 cm

Circumference (C)

= πd

= 3.14 * 28

= 87.92
