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

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
