Q1:- Find the circumference of
3circle whose radius is 14 cm.
44cm
88cm
42cm​

Answer 1

Answer:

Area of a circle

= 2πr

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

[ π = 22/7 ]

$\times = 2 \times \frac{22}{7} \times 14 \\ = \frac{44}{7} \times 14 \\ = \frac{616}{7} \\ = 88$

Therefore, the circumference of the circle is 88.
