Answer 1

We are given a circle with a diameter of 72 ft. We are asked to determine its area. To do that we will use the following formula:

`A=(\pi D^2)/(4)`

Where "D" is the diameter. Replacing the values:

`A=((3.14)(72ft)^2)/(4)`

Solving the operations:

`A=4069.44ft^2`

Now we are asked to determine the circumference of the circle, to do that we use the following formula:

`C=\pi D`

Replacing the values:

`C=(3.14)(72ft)`

Solving the operations:

`C=226.08ft`

Since the circumference is the measure of the longitude of the circle, if it were to be surrounded by tape this is the measure we would have to use.
