Question

The radius of a circle is 4.9 in. Find the circumference
to the nearest tenth.

Answer 1

Circumference = 2 * pi * r
2 * pi * 4.9 = 30.78761
Round to nearest tenth
Solution: 30.8 in.

Answer 2

C = 30.8

Explanation:

Circumference of a Circle:

C = 2πr

C = 2(3.14)(4.9)

C = 30.772

C = 30.8
