What is the answer to this ? need help on this homework

Answer 1

Answer:

18 units

Step-by-step explanation:

You have that V = 1/3 * pi * r^2 * h and V = 150 * pi and r = 5, so you substitute those second two values into the first equation.

150pi = 1/3 * pi * 5^2 * h

simplifying the left side,

150pi = 25/3 * pi * h

divide both sides by pi

150 = 25/3 * h

divide both sides by 25/3

h = 18

Answer 2

Answer:

v=1/3pie r^2 h

150pie=1/3 pie 5^2 h

450 pie/ pie=25h

h=18
