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.
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
[tex]V=\pi r^2h[/tex]
So, the volume of drum is
[tex]\begin{gathered} V=\pi(7^)^2(9) \\ V=\pi\times49\times9 \end{gathered}[/tex]
Take π = 3.14
So, the volume is
[tex]\begin{gathered} V=3.14\times49\times9 \\ V=1384.74 \end{gathered}[/tex]
So the volume is 1384.74 inches cubed.
Final Answer: Option B is correct answer.
