Answer:
V = 900
Step-by-step explanation:
Given the equation and the value of the variables, we can use substitution and algebraic manipulation to solve for V
r = 10√V
[divide both sides by 10]
r/10 = √V
[square both sides to get rid of the square root]
(r/10)² = V
[symmetric property of equality]
V = r² / 100
[substitute]
V = 300² / 100
[solve]
V = 900
