Question

If the radius of a circle is 49cm.Find the circumference of the circle​

Answer 1

Remember circumference of circle = 2πr

Here r = 49 and π = 22/7

$2 \times \frac{22}{7} \times 49$

$2 \times 22 \times 7$

= 308cm is circumference

circle circumference =?

$\color{PURPLE}{SOLVE}$

circle circumference formula=$\color{blue}{2πr}$

π=22/7

= 2× 22/7× 49

=$\color{green}{308 cm.}$
