Question

The volume of a cylinder is given by the formula V²h, where r is the radius of the cylinder and h is the height.

Which expression represents the volume of this cylinder?
h = 2x + 7
TO
r=x-3
2xx³-12xx²-24 *x+63*
2x³-5x²-24 *x+63*

Answer 1

Answer: 2x³-5x²-24x+63

Explanation:

`(x-3)^2*(2x+7)=\\\\(x^2-6x+9)*(2x+7)=\\\\2x^3-12x^2+18x+7x^2-42x+63=\\\\2x^3-5x^2-24x+63`
