Question

The radius of Paula’s wagon wheel is 10 1/2 in. What is the circumference of Paulas wheel?

Answer 1

Step-by-step explanation

The length of a circumference with radius r is given by:

`l=2\pi r.`

Replacing the value r = 10 1/2 in = 10.5 in, we get:

`l=2\pi*10.5in=21\pi\cdot in\cong65.97in.`Answer

The length of the circumference is 21π in or approximately 65.97 in.
