Question

Find the circumference of the given circle.
(Take $\pi$ as $\frac{22}{7}$)

• A. 8 cm
• B. 88 cm
• C. 120 cm
• D. 132 cm

Answer 1

The correct option is D

132 cm

Circumference = 2πr, where r is the radius of the circle.

Given that $\pi =\frac{22}{7}$

$\therefore \text{Circumference}=2\times \frac{22}{7}\times 21=132cm$
