What's the circumference of a circle with a radius of 7 in? Round your answer to the nearest inch.

Solution:

Radius of a circle = 7 in

We know that

Circumference of a circle = 2πr

Where r is the radius

Substituting the values

= 2 × π × 7

= 14π

= 43.9823 ≈ 43.98 in

Therefore, the circumference of a circle is 43.98 in.

What's the circumference of a circle with a radius of 7 in? Round your answer to the nearest inch.

Summary:

The circumference of a circle with a radius of 7 in is 43.98 in.
