X = 1st number, y = 2nd number, z = 3rd number
x + y + z = 26
y = 2x
z = 2x + 6
x + (2x) + (2x + 6) = 26
5x + 6 = 26
5x = 26 - 6
5x = 20
x = 20/5
x = 4 <=== first number
y = 2x....y = 2(4) = 8 <=== second number
z = 2x + 6....z = 2(4) + 6 = 8 + 6 = 14 <=== third number

Hey there :)
The volume formula of a cylinder is:
V =
r²h
The volume of the larger volume is given to be 9648³ and the height is 18 in
We need to find the radius first
9648 =
r²(18)
=
r²
536 =
r²
= r²
= r
r ≈ 13.06
The ratio of the big cylinder to small cylinder is:
18 : 9 (given height)
So the big cylinder is
2 times bigger than the small cylinder
Therefore the radius of the big cylinder is as well 2 times bigger
r ≈ 6.53 ( the radius of the small radius )
V (of small cylinder) =
(6.53)²(9)
= 1206 in³
