Answer:
The formula for the volume of a hemisphere is:
V = (2/3) * pi * r^3
where
V = 10,109.25 cubic millimeters
Solving for r:
r = [(3V) / (4pi)]^(1/3)
r = [(3 * 10,109.25) / (4 * pi)]^(1/3)
r = 16.9 mm (rounded to the nearest tenth)
Therefore, the radius of the hemisphere to the nearest tenth is 16.9 mm.
So, the answer is B-16.9mm.
