Question

The volume of a cylinder is given by the formula ="V+ \pi r^2h" alt="V+ \pi r^2h" align="absmiddle" class="latex-formula">, where r is the radius of the cylinder and h is the height. Suppose a cylindrical can has radius (x + 8) and height (2x + 3). Which expression represents the volume of the can?

Answer 1

V = $\pi r^{2}h$ where r is radius and h is height

so when radius is (x+8) and height is (2x+3),

volume = $\pi (x+8)^{2}(2x+3)$

Answer 2

Since your trying to find the volume of a cylinder and this is your formula V = πr²h you would write the equation with ( x + 8 ) as your radius and ( 2x + 3 ) as your height. The final equation for this would be π ( x + 8 )² ( 2x + 3) that would be the proper equation.
