Question

If the smaller cylinder has a lateral area of approximately 126 square meters, what is the approximate lateral area of the larger cylinder?

Answer 1

32

Answer 2

same radii?

Answer 3

Think of this in terms of a ratio. The ratio of the height of the cylinders is 8:20...which reduces down to what?
Now multiply the reduced ratio times the approx. area of the smaller cylinder and you should have your answer.
