Acylinder has a height that is 2 times as large as its radius. the lateral area of the cylinder is 16π square units. what is the length of the radius of the cylinder?
( show work)

2 units

Step-by-step explanation:

The lateral area of the cylinder is given by :-

, where r is radius and h is the height of cylinder.

Given: The lateral area of the cylinder = 16π square units.

Let r be the radius of the triangle, then we have

Height of cylinder = 2r

The lateral area of the given cylinder will be :-

Hence, the length of the radius of the cylinder = 2 units.

No he is incorrect. Frankie had not factored the 4/5th.

Step-by-step explanation:

All you have to do is make the denominators the same by multiplying  4/5 by 2. once you do that you should get 8/10.

so the answer would be 10 7/10< 10 8/10
