Answer:
1/4πs^3
Step-by-step explanation:
The volume of a cylinder = πr^2h.
Here its height h = s and its radius r = 1/2 diameter = s/2.
So it's volume is π(s/2)^2s
= 1/4πs^3.
Answer:
50+15=65
Step-by-step explanation:
I know because it says total
Answer:
Step-by-step explanation:
First, let x be the amount of 20% acid solution in liters. With this, 60 - x is the amount of 50% solution. The acid balance before and after mixing becomes,
(0.2)(x) + (0.5)(60 - x) = (0.40)(60)
The value of x is 20. Therefore, Gabe needs 20 liters of 20% acid solution and 40 liters of 50% acid solution.
