Zoe, Aria, and Evelyn are working on a school project where they need to determine the volume of a cylindrical water tank in their school. They are asked to use 3.14 for pi and round their answer to the nearest tenth. (Enter only a number; do not include a label on your answer.)
The diameter is 5mi and the height is 16mi
To find the volume of the cylindrical water tank, we need to use the formula:
Volume = pi * radius^2 * height
Given that the diameter is 5mi, we can find the radius by dividing it by 2:
radius = diameter/2 = 5mi/2 = 2.5mi
Now, we can substitute the values into the volume formula:
Volume = 3.14 * (2.5mi)^2 * 16mi
Simplifying:
Volume = 3.14 * 6.25mi^2 * 16mi
Volume = 3.14 * 100mi^3
Volume = 314mi^3
Rounding the answer to the nearest tenth: 314.0
Therefore, the volume of the cylindrical water tank is approximately 314.0 cubic miles.
The radius is 5
Apologies for the confusion. If the radius of the water tank is indeed 5 miles, we can calculate the volume using the formula:
Volume = pi * radius^2 * height
Substituting the given values:
Volume = 3.14 * (5mi)^2 * 16mi
Simplifying:
Volume = 3.14 * 25mi^2 * 16mi
Volume = 1256mi^2 * 16mi
Volume = 20096mi^3
Rounding the answer to the nearest tenth: 20096.0
Therefore, the volume of the cylindrical water tank is approximately 20096.0 cubic miles.
