Volume of the hemisphere = 14.4in³
First, we need to use the formula for the volume of a hemisphere.
2/3 x π r³
The only value we need to find here is the radius.
The radius is half the diameter.
So we divide 3.8in by 2.
3.8 ÷ 2 = 1.9in
R = 1.9in
Now, we can substitute these values into the formula above.
Volume of hemisphere = 2/3 x π x 1.9³
= 14.3654560073
Nearest tenth
= 14.4in³
