What is the circumference of a circle with a radius of 6 units?

Solution:

The circumference of a circle = 2πr units (where r denotes the radius of the circle).

For the given circle, 

Circumference = 2πr

= 2 × π × 6 [given radius = 6 units]

= 12π

Taking π = 3.14, 

12π = 37.68 units 

Hence the circumference of a circle with a radius of 6 units is 12π or 37.68 units.

What is the circumference of a circle with a radius of 6 units?

Summary:

The circumference of a circle with a radius of 6 units is 12π or 37.68 units
