Answer:
First option: True.
Step-by-step explanation:
To know if the volume of this cylinder is 496.21 ft³, you need to use the formula for calculate the volume of a cylinder:

Where "r" is the radius and "h" is the height.
You can observe in the figure that the radius of the cylinder is 4.5 feet and the height is 7.8 feet.
Then, knowing this, you can substitute these values into the formula.
Therefore, the volume of this cylinder is:

Then the answer is: True.
Answer:
50.2655
You see here, you find the diameter, which is 4, and multiply it. π
In conclusion, it is;
r = 2 m
V = 33.5103 m3
A = 50.2655 m2
C = 12.5664 m
Answer:
