Answer:
Answer:
D pi/4, 3pi/4
Step-by-step explanation:
Differentiate the function then equal it to zero and solve for the interval (see attached workings)
5 is the answer. 100% of any number is that number
So then we do
large-small
V=(1/3)hpir^2
given
small=r=3 and h=5
V=(1/3)5pi3^2
V=5pi3
V=15pi
large, r=5, h=12
V=(1/3)5pi12^2
V=5pi48
V=240pi
large-small=240pi-15pi=225pi in^3
