B Correct answer
Explanation

Volume of a hemisphere = (2/3) * pi * r^3. 155232 = (2/3) * (22/7) * r^3. r^3 = 155232 * 3 * 7 / (2 * 22) = 74088. r = cube root of 74088 = 42.

AI explanation

Using the hemisphere volume formula, two thirds multiplied by pi multiplied by the cube of the radius equals 155232. Substituting pi as 22 divided by 7 gives the cube of the radius as 74088. The cube root of 74088 is 42 cm.
