volume = (pi) r^2 h
so sub in stuff..
48 pi = pi 4^2 h
h=48/16
h=3 in.

Volume of a cylinder is π r^2 h
48 π = π 4 x 4 x h
h = 3

Volume = base * height
the base of the cylinder is a circle
Volume = π r² h
Given that the volume is 48π
48π = π (4)² h
16h = 48
h = 3 in

a million. the backside element of 64?=?R^2 so the radius of the backside is 8 ... the top is 12 once you narrow back 9 inches (you could't be "above" the vertex) under the vertex the best triangle has a base radius given by the expression: r/R = 9/12 because of the fact the triangles formed are comparable ... so r=9*8/12 The cut back base section then is: A=?(9*8/12)^2 = ?(3*3*4*2/4*3)^2 = 36? If the cut back is 9 inches above the backside...you do a similar situation making use of the similsr triangles, yet you will get a distinctive answer

Volume = pi r^2 H
r = radius
H = height
V = 48pi = pi (4)^2 H
48pi = 16pi H
H = 3 inches
Hint: In the future just search for the formula of interest.
Good luck

height of cylinder is given by
h = volume/pi(radius)^2
= 48pi in^3/pi(4in)^2
= 3 inch
