Answer:
121.9
Step-by-step explanation:
I will use pi but not in the answer
use formula V=πr²h
(π)(3.5²)(5.5)
12.25 × 5.5=67.375 × π=211.6648...
1/2(4/3(π(3.5³))
4/3(42.875)=57.166...× π = 179.59438...
1/2(179.59438...) = 89.79719...
211.6648... - 89.79719... = 121.86761... ≈ 121.9
Well I figured it out and I came up with 13 square inches. you can find this out by doing the square root of 169. I hope this help :).
This becomes...........
[(y+7)/7y] x [(14y-5)/(3y^2+21y)]= [(y+7)/7y] x [(14y-5)/3y(y+7)]= [1/7y] x [(14y-5)/3y]= [(14y-5)/21y]
