No because there is no picture and circles
I cant help you on this if there is no coefficients.
Answer:
the formula is C = 2(pi)r
To get the answer, do 30,00 / 8
after dividing that you will get the answer 3,750
3/4 - 1/8 = 6/8 - 1/8 = 5/8...so 5/8 = 10 gallons
(5/8) / 10 = 1 / x
cross multiply
(5/8)(x) = (10)(1)
5/8x = 10
x = 10 * 8/5
x = 80/5 = 16 <== so it would take 16 gallons to fill the tank
