Question

If the smaller cylinder has a lateral area of approximately 113 square meters, what is the approximate lateral area of the larger cylinder?

48.4 square meters
263.7 square meters
615.2 square meters
1,435.5 square meters

Answer 1

hmm you aren't given much info so what i would do is just a ratio. i'm assuming they're proportional and i'm not 100% sure this is how you do the question but if they are indeed proportional then you have 113 m^2 / 9m = ? / 21m

Answer 2

I agree. So
113/9 = x/21
x = (113/9)*21
x = 263.7, which is one of the choices so you are right.

Answer 3

Oh, I forgot to add 9. I was only using the bigger cylinder
