Answer:

Area of circle, A = 616 cm^2

Step-by-step explanation:

Area of circle:

A = πr^2

Given: d = 28 cm and π = 22/7

so r = d/2 = 28/2 = 14 cm

So

A = π r^2

A = 22/7 * 14^2

A = 22/7 * 196

A = 616 cm^2

Diameter is= 28cm

Radius equals to 14

Area equals to πr*2

So 14*2=196

196π equals to 615.75
