The circumference (c) c of a swimming pool is 56 feet. which formula can you use to find the diameter (d) d if you know that c=πd

Since you are solving for diameter, and the equation is given to you, just isolate the variable for diameter (d).

(C)/π = (πd)/π

d = C/π is your formula you will use.

Plug in 56 for C

d = 56/π

d = ~17.825
