Answer: 63pi cm³
Step-by-step explanation: To find the volume of a cylinder, start with the formula for the volume of a cylinder.
[tex]Volume = \pi r^{2}h[/tex]
In this problem, our cylinder has a radius of 3 cm and a height of 7 cm so we can plug this information into our formula.
[tex]Volume = (\pi) (3 cm)^{2} (16 cm)[/tex]
Let's start by simplifying the exponents. Remember that 3 cm² is equal to 3cm multiplied by 3 cm or 9 cm².
[tex]Volume = (\pi) (9cm^{2}) (7 cm)[/tex]
[tex]Volume = 63\pi cm^{3}[/tex]
