Question

if the radius of a circle is 12m then the circumference of a circle is

Answer 1

radius=12 m

circumference=2πr
=2*22/7*12
=44*12/7
=528/7
=75.4m

Answer 2

Answer:

Circumference of circle is 75.36 m.

Step-by-step explanation:

As per given information ,

Radius of circle is 12 m.

We have to find out the circumference of circle.

As we know that,

Circumference of circle = $2 \times \pi \times r$

Put the value of r ,

Circumference of circle = $2 \times \pi \times 12$

Circumference of circle = $24 \times \pi$

Put the value of π = 3.14

Circumference of circle = $24 \times 3.14$

Circumference of circle = $75.36$

Hence,

Circumference of circle is 75.36 m.
