A rain barrel is a right circular cylinder. If 1ft^3 =7.5 gallons, how many gallons of rainwater can the barrel hold?
Use 3.14
Barrel is 1.35ft left to right.... And 5ft top to bottom.

Find volume of right circular cylinder V = pie * r * r * h= 3.14 * 1.35/2 * 1.35/2 * 5 ft^3= 7.153 ft^3Since 1ft^3 = 7.5 gallons7.153 ft^3 = 7.5 * 7.153 gallonsi.e equal to 53.65 gallons
