Answer:
N=10
Step-by-step explanation:
The hemisphere is half the volume of a sphere. Since we are given the circumference, we can solve for the radius of the sphere. That is
Part A
We can now compute for the volume of the hemisphere.
Part B
We just need to convert the volume into its corresponding gallons
Namely, what is 170% of 2.80? well, if we take 2.80 to be the 100%, what is the 170%?
