Question

Find the circumference of the object. Use 3.14 or 22/7 for Pi. Round to the nearest hundredth if necessary.

Answer 1

`43.96 \text{ in}`

Explanation:

The equation for circumference is:

`C=2\pi r`

Using the diagram, we can conclude that the radius of the object is 7 in.

We can substitute this value in for the equation (Note that I will use 3.14 for π):

`C=2\pi r\\C=2*3.14*7\\C=14*3.14\\C=43.96\text{ in}`
