D Correct answer
Explanation

Volume = pi * r^2 * h. 4.62 = (22/7) * (0.7)^2 * h. 4.62 = 22 * 0.07 * h. 4.62 = 1.54 * h. h = 4.62 / 1.54 = 3.

AI explanation

Using the cylinder volume formula, V equals pi r squared h, we convert the radius of 70 cm to 0.7 m. This gives 4.62 equals 22 over 7 times 0.7 squared times h, so 4.62 equals 1.54 h. Solving for h gives a height of 3 m.
