A cylinder has a height that is 2 times as large as its radius. The lateral area of the cylinder is 16 {pi} square units. What is the length of the radius of the cylinder?

Question

superdavesuper · Answer

The lateral area = diameter x height okay? so what will that tell u?

Oooops....sorry wrong equation!

it should be lateral area = pi x diameter x height....

Lateral area $$A(r)=2 \pi r h = 4 \pi r^2=16 \pi \implies r=2$$is

Let radius = r units ==> ht = 2r units
A = 2πrh
2πr(2r) = 16π
4r^2 = 16
r = 4 units
