Question

Radius of circle is 22 cm. Find the perimeter of circle

Answer 1

Step-by-step explanation:

radius of circle is 22 CM

perimeter of circle is 2πr

$2 \times \frac{22}{7} \times 22$

$\frac{968}{7}$

$138.28 {cm}^{2}$

Answer 2

Answer:968/7 or 138.285714286

Step-by-step explanation:

Perimeter is same as circumference

Formula for circumference = 2$\pi$radius

Radius = 22cm

Pi = $\frac{22}{7}$

∴ Circumference = $\frac{22}{7}  * 2 *22$

=$\frac{968}{7}$
