Question

If the radius of the bagels whole is 0.75 in what is the whole circumference in inches

Answer 1

The circumference of a circle of radius r is given by:

`C=2\pi r`

Substitute r=0.75 to find the circumferece:

`\begin{gathered} C=2\pi(0.75) \\ =1.5\pi \\ \approx4.71 \end{gathered}`

Therefore, the circumference is equal to 1.5π inches, which is approximately 4.71 inches.
