Question

can someone make r the subject please:
V=(1/3)pi r^2 h

Answer 1

v=(1/3)pir^2h.
first can divide 1/3 to v which we get
3v=pir^2h.
then we divide by pi and h which we get
3v/(pih)=r^2
from there we square root everything to both sides so we can solve for r, which we get
the square root of 3v/(pih)=r.

Answer 2

why when you divided by 3 its 3v??
i thought 3v is when you times it :S

Answer 3

v
----- = v * 3/1 = 3v
1/3

Answer 4

oh ok, thanks :)
