Mathematics
1 answer:
alex41 [277]3 years ago
4 0

Answer:

Step-by-step explanation:

V = 1/3 pi r^2 h                Multiply both sides by 3

3V = pi r^2 h                   Divide by pi * h

\frac{3*V}{\pi * h}    = r^2                       Take the square root

\sqrt{\frac{3V}{\pi*h} }      = r

Simplify x²-49/3x+21
Vera_Pavlovna [14]
First, you factor and simplify (respectively) the numerator and denominator. Your equation becomes:

\frac{(x-7)(x+7)}{3(x + 7)}

Notice, there is a (x + 7) on both the top and the bottom. Because of this, they cancel each other out. What is left is your answer:

\frac{(x-7)}{3}
