Answer:
True
Step-by-step explanation:
x - 4y = 11 → (1)
- 3x + 5y = 25 → (2)
Multiply (1) by 5 and (2) by 4 to eliminate the y- term
5x - 20 y = 55 → (3)
- 12x + 20y = 100 → (4)
Add (3) and (4) term by term to eliminate y
- 7x + 0 = 155
- 7x = 155 ← y- term is eliminated
B. Negative

A=640.88
if the diameter is 12, the radius , r=12/2=6
we have r=6, h=11
Surface area, A= 2πrh+2π r^2
A=2*3.14*6*11+2*3.14*(6)^2=640.88
i think these inequalities shows B
3/10
Hope it helps
