The height of a right cylinder is 3 times the radius of the base. the volume of the cylinder is 24 cubic units

Let the radius of the base be r units

Then the height will be 3r units

Volume of cylinder = pi r^2 h

24=pi r^2 × 3r

Pir^3 = 24/3

Pi r ^3 =8

r^3 = 8/pi

R = 2 / pi^1/3

Height = 6/pi^1/3

step-by-step explanation:

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
