Final answer:
To calculate the volume of a hemisphere with a diameter of 3.8 inches, you can use the formula V = (2/3) * π * r^3. Substitute the values and calculate to find the volume, then round to the nearest tenth of a cubic inch.
Step-by-step explanation:
The volume of a hemisphere can be calculated using the formula V = (2/3) * π * r^3.
In this case, the diameter of the hemisphere is 3.8 inches, so the radius will be half of that, which is 1.9 inches.
Substituting the values into the formula, we get V = (2/3) * π * (1.9)^3.
Calculating this expression gives us the volume of the hemisphere. Finally, we round the result to the nearest tenth of a cubic inch.
