Question

I need help with this question so bad. Please help!

Okay okay heres the question:
The volume of a hemisphere is 10,109.25 cubic millimeters. What is the radius of the hemisphere to the nearest tenth?
A-14.9mm
B-16.9mm
C-19.8mm
D-29.8mm
ALL HELP IS NEEDED THANKS!

Answer 1

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.
