Question

a cylinder has a radius of 4x + 2 and a height of 5x + 4. What is the volume? The Solution Should be in standard form and use V = π r^2 h.

Answer 1

v = πr^2 h = π(4x+2)^2 (5x+4)
now expand that out
maybe factor out the π just to make things easier to read.

Answer 2

@oobleck that helped a lot! Thank you!
