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

How can you determine whether a given number makes an equation true?​
EastWind [94]

Answer:

By plotting in the number in the equation (aka where all the x’s are variables are) and seeing if it works.

Step-by-step explanation:

For example, let’s use the problem:

3x + 4 = 16

if the given number is 4, we fill it in for x-

3 (4) + 4= 16

solve to see if true:

12 + 4 = 16

16 = 16

hence, the given number 4 makes the equation true!

hopes this helps, have a great day :)

Notice the picture below

see where that angle is?

check your Unit Circle for that value

also notice, that fractions of \pi are just like grabbing 180 degrees and splitting it, so one third of 180 or \pi is 180/3 or 60 degrees
