Question

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

Answer 1

The circumference of a circle with a radius of 7 inches would be 43.98 inches. But rounded to the nearest inch it would be 44 inches.

Answer 2

44 inch

Explanation:

formula for the circumference is:

Circumference [C] = Pi[π] × Diameter of the circle[D].

The diameter is = the radius × 2

∴ D = 7×2

= 14

∴ C = π×D

= π×14

∴C = 44 inch.
