Question
I'm suppose to find the radius of a sphere where volume = 32pi/3
and i'm lost completely.
Teresa,
The formula for the volume of a sphere is V=(4/3)*pi*r^3.
May I suggest that you look up a tutorial on the web.
Here, given V=32*pi/3, we set it equal to (4/3)*pi*r^3 and solve for r.
r=[(3/4)*V/pi]^(1/3)
note: x^(1/3) means the cubic root of x.

When I work through problems, I like to emphasize concepts which I believe are worth noting. I will try to answer questions in the following areas, but not at the advanced level. Algebra. Sequences & Series. Trigonometry. Functions & Graphs. Coordinate Geometry. Quadratic Polynomials. Exponential & Logarithms. Basic Calculus. Probability, Permutation and Combination. Mathematical Induction. Complex numbers. Physics problems.

I have worked as a teaching assistant in college. My hope is that more people will share knowledge without boundary, give help without seeking recognition or monetary rewards.
