A cylindrical water tank has a radius of 2 feet and a height of 5 feet. If 1 cubic foot of water is approximately 7.48 gallons, how many gallons of water can the tank hold when full? (Use π ≈ 3.14)

A 31.4 gallons

B 157.0 gallons

C 235.5 gallons

D 469.88 gallons

✓ Correct Answer: Option C

First, find the volume of the cylinder: V = πr²h = 3.14 * (2²) * 5 = 3.14 * 4 * 5 = 62.8 cubic feet. Then, convert cubic feet to gallons: 62.8 * 7.48 ≈ 469.88 gallons.
