First, view how i converted the mixed fraction in the picture.
Next, we need to get the same denominator,
46/3 divided by 23/6, 6 and 3; all we do is times 3 by 2 to get 6 and time six by 1 to stay the same.(Tip: every thing you do to the denominator you do to the numerator.
= 46*3=92 , 3*2=6 other fraction, 23*1=23 , 6*1=6
Our fractions now look like this,
92/6 and 23/6
We can now divide.
23 can go into 92, 4 times, so 4/6 , now simplify =
Answer= 2/3

Answer:
= r
Step-by-step explanation:
V = 1/3 pi r^(2) *h
Rewrite:
V = pi * r^(2) * h/3
Inverse operations:
V / h / 3 = pi * r^2
Simplify:
3V/h = pi * r^2
Inverse operations:
3V/h / pi = r^2
Simplify:
3Vpi/ h = r^2
Inverse operations:
sqrt( 3Vpi/h) = r
= r
