What is the volume.?

Question

A cylinder hotel is 68 stories high. If the height of this cylinder is 733 ft and its diameter is 92ft, what is the volume?

Answer 1

 V = pi * radius^2 * height

 

V = pi * 46^2 * 733 = 4872698.170312069....

 

Notice they give you the diameter, but the formula

requires the radius, which is half the diameter.
