Volume = Pi r^2 h
= Pi (4x+2)^2 (5x-4)
= Pi (16x^2 +16x + 4)(5x^2 - 4)
without completing the whole expansion, I know it has to start with
80Pi x^3 and end in -16Pi
The only answer that matches that is C
A cylinder has a radius of 4x + 2 and a height of 5x — 4. Which polynomial in standard form
best describes the total volume of the cylinder?
A.80pix^3+144pix^2+84pix+16pi
B.20pix^2+26pix+8pi ****
C.80pix^3+144pix^2+84pix-16pi
D.400pix^4+1040pix^3+996ix^3+416pix+64pi
My answer has the "***"by it. Please check my answer
Thanks

Don't trust any answers that are just letters especially for tests...
In connexus some of the tests have different questions for everyone so it isn't reliable
