Question

A circle has a radius of 15 cm which of these is the closest to it circumference

Answer 1

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

`C=2\pi r`

So, using pi = 3.14 and r = 15, we have:

`\begin{gathered} C=2\cdot3.14\cdot15 \\ C=94\text{ cm} \end{gathered}`

Therefore the correct option is the second one.
