Volume is 4/3(3.14)(r)^2
the radius is 5.2 ft
Take the root of both sides and solve.
8 * 5 = 40
40 * 4 = 160
160 * 12 = 1,920
Answer: $1,920
Work in amount of pure acid let x = gallons of pure acid required.
then we have the equation:-
x + 55(0.6) = 0.80(x + 55)
x + 33 = 0.80x + 44
0.20x = 11
x = 11/0.2 = 55 gallons answer
