solve for r when v=4/3*3.14R^3
2006-09-02 07:14:17 · update #1
V=(4/3)(pi)(R^3)
multiply both sides by 3/4
3V/4=(pi)R^3
divide both sides by pi
(sV)/(4pi)=R^3
so for finding R now find the cube root of (3V)/(4pi)
you can use 3.14 for pi
so R is cube root of (3V)/(4)(3.14)

Solving for R as a cube is too hard, so try this:
You are starting with V= (4 over3) pi (R cubed).
Rearrange it like to be R= V over 4 pi (R squared).
Now it should be more manageable.

Given:
V = (4/3)Ï r^3
V/ (4/3)Ï = r^3
Cubed root of [V/ (4/3)Ï] = Cubed root of (r^3)
[V/ (4/3)Ï]^1/3 = r

You have two variables and only one equation.
"v=3/4piR^3?"

V = (4/3)pi * r^3
3V = 4pi * r^3
(3/4)(V/pi) = r^3
r = cbrt((3V)/(4pi))
