Answer 1

Given: Jasper is a drummer in his school’s marching band. He carries a marching snare drum that has a radius of 7 inches and a height of 9 inches.

Required: Volume of the drum.

Step-by-step explanation:

The drum is in the shape of a cylinder.

It has radius, r = 7 inches

and height, h = 9 inches.

Volume of cyliner, V is

`V=\pi r^2h`

So, the volume of drum is

`\begin{gathered} V=\pi(7^)^2(9) \\ V=\pi*49*9 \end{gathered}`

Take π = 3.14

So, the volume is

`\begin{gathered} V=3.14*49*9 \\ V=1384.74 \end{gathered}`

So the volume is 1384.74 inches cubed.

Final Answer: Option B is correct answer.
