Answer:
1922.7 cubic inches
Step-by-step explanation:
The volume of a cylinder can be found with this formula:
V=πr^2h
The radius, r, is half the diameter.
So, 12/2=6
r=6 inches
Then, just plug the numbers in.
V=π(6)^2(17)
V=1922.65
Rounding to the nearest tenth:
V=1922.7 cubic inches

Step-by-step explanation:
n + n+1 + n+2 + n+3 = 4n + 6
4n + 6 = 34
4n = 28
n = 7
Eldest: n + 3 = 7 + 3 = 10
