How would I solve this problem?
You were asked to design a sphere with a volume of 128cm3. What should the diameter of the sphere be?
Thanks.
Hi andi.
The volume of a sphere is found by the formula $\displaystyle V = \frac{4}{3}\pi r^3$ where $\displaystyle r$ is the radius of the sphere. Remember, radius is twice the diameter.
Therefore we get:
$\displaystyle 128 = \frac{4}{3}\pi r^3$
$\displaystyle r^3 = \frac{96}{\pi}$
I'm sure you can work this out now
