Question

Find the circumference of circle whose diameter is 2.5 m

Please help me

Answer 1

7.8539 m

Explanation:

Multiply 2.5 by 3.14159

Answer 2

7.85 m

Explanation:

Circumference is 2πr.

The radius (r) is half of the diameter, but multiplying r by 2 is the same as just using the diameter in this formula, so:

2.5π

When you multiply you get 7.85 to the nearest hundredth.
