To evaluate when plugging in numerical values for variables, simply put the numerical values in the place of the corresponding variables:
[tex] V = \pi \cdot 3^2 \cdot 5 [/tex]
[tex] \boxed{V = 45\pi \approx 141.37} [/tex]
[tex]V=\pi R^2h[/tex]
It's the formula of a volume of a cylinder :)
Put the values of r = 3 and h = 5 to the formula:
[tex]V=\pi\cdot3^2\cdot5=\pi\cdot9\cdot5=45\pi[/tex]
