The rain barrel shown is a right circular cylinder. if 1ft^3=7.5 gallons, how many gallons of rainwater can the barrel hold if the height is 5ft and the top of the barrel is 1.68ft?

this can be solved using the fomula of the volume of a right circular cylinder

V = pi*r^2*h

Where pi = 3.1416

R is the radius

H is the height

V = 3.1416(1.68^2) (5)

V = 44.3342 ft^3 (7.5 gallon / 1 ft^3)

V = 332.5062 gallons
