we know that

The volume of a cylinder is given by the formula

V=3.14 r^{2} h

where

r is the radius of the cylinder

h is the height of the cylinder

in this problem

r=x+8\\h=2x+3

Substitute the values in the formula above

V=3.14*(x+8)^{2}*(2x+3)

V=3.14*(x^{2}+16x+64)*(2x+3) \\ V=3.14 *(2x^{3} +3x^{2} +32x^{2} +48x+128x+192)\\ V=3.14*(2x^{3} +35x^{2} +176x+192)

therefore

<u>the answer is</u>

The volume of the can is equal to

V=3.14 *(2x^{3} +35x^{2} +176x+192)\ units ^{3}
