Question

Help I'm practicing

Answer 1

Step 1: Write out the formula

`C=\pi D`
`\begin{gathered} \text{where} \\ C=\text{ the circumference of the circle} \\ D=\text{ the diameter of the circle} \end{gathered}`

Step 2: Write out the given value and substitute it into the formula

`D=19\text{ inches}`

Therefore,

`C=\pi*19in\approx60\text{inches}`

Hence, in inches, the circumference is approximately 60
