Question

The volume of a cylinder is given by V = ar?h

where ris the radius of the cylinder and his the
height. Which expression represents the volume of
this can?​

Answer 1

D

Explanation:

`V=\pi r^(2)h\\ =\pi*(x+2)*(x+2)*3x+8\\ =\pi *x(x+2)+2(x+2)*3x+8\\ =\pi *x^(2)+4x+4*3x+8\\ =3x(x^(2)\pi+4x\pi+4\pi)+8(x^(2)\pi+4x\pi+4\pi0 \\ =3x^(3)\pi+20x^(2)\pi+44x\pi+32`
