Question

Find the circumference of the circle. Round to the nearest hundredth if necessary. (Use 3.14 for me) A circle with a diameter of 6.2 in

Answer 1

Remember that the formula for the circumference of a circle is:

`C=2\pi r`

Since the diameter is twice the radius,

`6.2/2=3.1`

Our cirlce has a radius of 3.1".

Using this and the data given, we get that:

`\begin{gathered} C=2(3.14)(3.1) \\ C=19.468 \end{gathered}`

Therefore, the circumference would be 19.468 inches
