A cylindrical mailing tube has a length of 20 inches and diameter of 4 inches. O
What is the approximate volume of the cylinder, to the nearest tenth of a cubic inch?
(Use 3.14 for pi.)

Volume = 251.2 cubic inches

Step-by-step explanation:

You get the volume of a cylinder by multiplying the area of the base with the height.

Since the diameter is 4 inches, the radius of the base is 4/2 = 2 inches

So, volume = base area* height

                  = 2² * 3.14 * 20

                  = 251.2

it would open into a square depending on the type of envelope i’m not sure about the second part

it would not be increasing by nothing that i can see probably by 25 percent that is all i can sat\y for now if i have any thing else to say i will edit this.
