help me im really bad at this stuff

Answer:
We conclude that the estimated volume of a cylinder is 288 in.³
Step-by-step explanation:
Given
The formula to determine the volume of a cyliner is:
[tex]V=\pi r^2h[/tex]
substituting the values r = 3.75 inches, h = 6.21 inches, and π = 3.14 in the formula to calculate the volume of a cylinder.
[tex]V=\pi r^2h[/tex]
[tex]V=\left(3.14\right)\left(3.75\right)^2\times 6.21[/tex]
[tex]V=274[/tex] in.³
Therefore, from the given options, we conclude that the estimated volume of a cylinder is 288 in.³
