    Answer:

    (2) 2,640 ft

    Step-by-step explanation:

    I’m going to assume that in this question, you are walking 1 full circle around the reservoir. That would mean you need to calculate the circumference of the circular reservoir.

    The circumference formula is:

    C = ⫪d

    C stands for Circumference

    d stands for diameter

    I will use 22/7 instead of pi, so the formula looks more like this:

    C = (22/7)(d)

    The diameter is 840 feet, so we will substitute the variable d with 840:

    C = (22/7)(840)

    You can plug this part into the calculator, but by hand, it’ll look something like this:

    (22/7)*840 = (22*840)/7

    18,480/7 = 2.640

    Hope it helps (●’◡’●)
