Question

Find the circumference of the circle with radius 21 cm (π = 22/7)​

Answer 1

It is given that,

Radius of a circle = 21 cm.

We know that π=22/7,

So the circumference of a circle = 2πr

Substituting the values,

=2∗22/7∗21

So we get,

=2∗22∗3

=132

Answer 2

Step-by-step explanation:

circumference of circle is 132cm

You can convert it into SI unit 1m=100cm

then 132/100=1.32m
