Let r denote radius.

To find circumference we use


C=2\pi r=28\pi\approx\boxed{87.92\mathrm{cm}}

To find area we use


A=\pi r^2=196\pi\approx\boxed{615.44\mathrm{cm^2}}

Hope this helps.

Answer:

Explanation:

r = 14 cm

Circumference = 2πr = 2*22 *14/7 = 2 * 22 * 2 = 88 cm

Area =πr² = 22 * 14 *14 /7 = 22 * 14 *2 = 616 sq.cm
