Question

A basketball has a diameter of 8 inches. What is the distance around it?

Answer 1

Assuming that the distance arund it refers to the circumference of a circle with the same radius, then, remember that the circumference of a circle is equal to π times its diameter:

`C=\pi D`

Since the diameter is 8 inches, then:

`\begin{gathered} C=\pi*8\text{in} \\ =25.13274123\ldots\text{in} \\ \Rightarrow C\approx25.1in \end{gathered}`

Therefore, the distance around it is approximately 25 inches.
