Question

Joshua just bought a new fish tank. The tank is 14 inches tall and has a radius of 4 inches. How much water can Joshua put in the tank? Use 3.14 for pi. *

A. 703.36 cubic inches
B. 56 cubic inches
C. 224 cubic inches
D. 175.84 cubic inches

Answer 1

V = 703.36 in³ (This matches answer option A.)

Explanation:

This fish tank has a cylindrical shape. The formula for the volume of a cylinder of radius r and height h is

V = (pi)(r²)(h).

We are told that h = 14 in and r = 4 in. Using 3.14 for pi:

V = (3.14)(4 in)²(14 in) =

V = 703.36 in³ (This matches answer option A.)
