Question

a circular sinkhole has a circumference of 75.36 m s made the diameter of the sinkhole round to the nearest meter

Answer 1

We will determine the diameter by using the circumference formula, that is:

`C=2\pi r`

Now, we replace the values and solve for the radius (r):

`75.36=2\pi r\Rightarrow r=(75.36)/(2\pi)\Rightarrow r\approx12`

Now, since we know that the diameter of the circle is two times the radius then the diameter is approximately 24 m.
