Can someone me to find the solution ?

We know, Volume of a Cylinder = πr²h

V = π * (0.975)² * 5

V = 3.14 * 0.950 * 5

V = 14.92 ft³

Here, 1 ft³ = 7.5 gal

Then, 14.92 Ft³ = 14.92 * 7.5 = 111.93 Gal

In short, Your Final Answer would be: 112 Gallons

Hope this helps!

V = π•r^2•h
r = 0.975 ft
h = 5 ft

V = (3.14)(0.975^2)(5)
V = (3.14)(0.950625)(5)
V = 14.9248125 ft^3
14.9248125• 7.5 = 111.9 gallons of water
