Question

Find the volume of a cylinder with a radius of 3 cm and a height of 7 cm.

Answer 1

The answer is 197.92 cubic cm

Answer 2

Answer: 63pi cm³

Step-by-step explanation: To find the volume of a cylinder, start with the formula for the volume of a cylinder.

$Volume = \pi r^{2}h$

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.

$Volume = (\pi) (3 cm)^{2} (16 cm)$

Let's start by simplifying the exponents. Remember that 3 cm² is equal to 3cm multiplied by 3 cm or 9 cm².

$Volume = (\pi) (9cm^{2}) (7 cm)$

$Volume = 63\pi cm^{3}$
