Answer 1

To solve this problem, we have to compute the circumference of a circle of diameter:

`d=840ft.`

Recall that the circumference of a circle is given by the following formula:

`C=d\pi,`

where d is the diameter.

Therefore, the circumference of the reservoir is:

`C=(22)/(7)*840ft=2640ft.`

Answer:

`2640ft.`
