The answer is C or x=-4.
Step-by-step explanation:
I hope this helps!
The height of the cylinder (glass 1) we call h so the volume is 4πh cc.
The volume of the cone is ⅓×2.5²×6π=12.5π cc.
If we divide 60 by π we get 19.11 cc approx.
So 4h+12.5=19.11, 4h=6.61 cc and h=1.7 cm approx, answer 2.
45.864, because 57.33 divided by 100 is 0.5733 that multiplied by 80 is 45.864
