4×2=8. 100×2=200
8% out of 200
so
4=8 if you have double, 200
First the 2 bases have surface area pi*1.25^2*2
Then the side
2.5pi*4=10pi
total of 9.817+31.415
=41.232
This approximation could be further round down for this problem to 41.2
Which makes choice C the correct choice.
Answer= x^2-4
I hope this helps.
