  radius= 28cm

  we know that perimeter of a circle= 2πR

  =>2×22/7×28=2x22x4=176 cm

  and area=<em style=”font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>πR^2

  <em style=”font-family: inherit; font-size: inherit; color: var(–bb-body-text-color);”>=>22/7x(28)^2=2464 cm^2
