Question

H 24 inches The volume of a cylinder can be found by using the formula v Bh. Which expression can be used to determine B, the area of the base of this hatbox in square inches? (24) H 82.12 J 122.8

Answer 1

The volume a cylinder is v=(area of base)h and since the area of the base is πr², you can write the equation a v=πr²h.  Since the problem wants us to find what be is in the equation of a cylinder as v=Bh, we know that B=πr².  The problem gave us the diameter of the circle so we no the radius is going to be the diameter (24) divided by 2 which equals 12.  therefore B=12²π.

I hope this helps.
