Cone Volume = (PI * radius^2 * height) / 3
3 = (PI * radius^2* x) / 3
radius^2 = 9 / (PI * x)
radius = square root (9 / (PI * x))
The answer would be: <span>√x+3=13
</span>A radical equation is an equation with at least one variable put on a radical form. In this question, there is only one kind of variable which is x. Then, you need to find the equation where x is in the radical form. The radical form can be expressed with square root symbol.
The option with √x would be only <span>√x+3=13

Answer:
3/4
Step-by-step explanation:
First you add 87 +89 which equals 176.
second you multiply all the numbers you want to divide, which, to save time, equals 69,120
176 / 69,120 = 0.0025462962963 (0.003 if needing to round)
