Answer:
254.5 Inches Cubed
Step-by-step explanation:
Formula for Finding the Volume of a Cylinder: [tex]V=\pi r^2h[/tex]
The radius is 3 inches.
[tex]r=3[/tex]
The height is three times the radius.
Multiply the radius by three to get the height.
[tex]h=3*3\\h=9[/tex]
The height is 9 inches.
Use the formula to find the volume.
[tex]\pi (3)^29= \pi (9)9=81\pi[/tex]
The exact volume is 81[tex]\pi[/tex] inches cubed.
[tex]81 * \pi[/tex] ≈ 254.47
254.47 ≈ 254.5
The volume of the cylinder should be about 254.5 inches cubed.
