Question

Find the circumference of a circle whose radius is 7 cm . please tell me the solution by one by one method​

Answer 1

Answer:

Circumference= 2*pi*r

Step-by-step explanation:

Then answer = 2*22/7*7

=44

Answer 2

$\large\frak{\underline{\underline{\pink{Solution:-}}}}$

Given that,

• Radius of the circle = r = 7 cm.

We know that,

• Circumference of the circle = 2πr

So,

Circumference of the circle :-

➩  2 × 22/7 × 7

➩  2 × 22

➩  44 cm.

∴ Circumference of the given circle (C) = 44 cm
