At work, Chad is designing a product proiſtype. Part of the product is a cylinder with a volume of 48 n cubic inches and a radius of 2 inches. When he presented the prototype to the company, they
decided the cylinder should have a volume of 72 cubic inches.
Based on this information, how much height will he need to add the original cylinder?

For a right cylinder, volume=π(radius)2(height). Since the volume of water is 36 cubic inches and since this represents 21 the container, the is occupying 21 the container's height, or 9(21)=4.5 inches. Let r be the radius of the cylinder.

36=πr2(4.5)

8=πr2 divide both sides by 4.5

π8=r2 divide both sides by π

π8=r take the square root of both sides

π22=r simplify the 8 to get the radius

Then, since the diameter is twice the length of the radius, the diameter equals

2(π22)=4pi2=4π2.

the answer is b i just did that
