Question

A dinner plate has a radius of 5 inches Find the circumference. Use 3.14 for TT and round to at least 1 decimal place. The circumference is——inches.

Answer 1

In order to calculate the circumference, we can use the formula:

$C=2\pi r$

Where r is the radius.

So, using r = 5 and π = 3.14, we have:

$\begin{gathered} C=2\cdot3.14\cdot5 \\ C=31.4 \end{gathered}$

So the circumference is 31.4 inches.
