Question

What is the circumference of a circle with a radius of 3 inches? Use 3.14 for pie

Answer 1

Answer: 18.84

First, the formula utilized to find the circumference of a circle is C=2πr.

So, C=2x3.14x3
2x3.14= 6.28
6.28x3= 18.84

Answer 2

18.85

Explanation:

1. Formula for finding circumference is C=2πr.

2. Plug in the numbers. C=2(3.14)(3)

3. Multiply. 2 x 3.14 = 6.28 6.28 x 3 = 18.84

4. Answer is 18.84 (or 18.85 if rounding)
