To find the radius of the sphere, we can rearrange the formula for the volume:
V = (4/3) * pi * r^3
Solving for r, we have:
r^3 = (3 * V) / (4 * pi)
r = cuberoot((3 * V) / (4 * pi))
Substituting V = 33.5 m^3 and pi = 3.14, we get:
r = cuberoot((3 * 33.5) / (4 * 3.14))
r ≈ 2.014
Rounding to the nearest whole, the radius is approximately 2 m.
Therefore, the correct answer is R. 2 m.
