Question

Given that radius of a circle is 14 cm, find its circumference and area​

Answer 1

Answer:

Step-by-step 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

Answer 2

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.
