The way it works is this: for your problem, you find a section of my( Igor's )  site that discusses your part of the algebra curriculum. <b>It is very important that you find the right section. </b>
What does pie sign mean?
I know pie should be pi but what is sign ? There are many math signs ( < > = - + * / sqrt )
Oh you mean pi for pie sign . We just say pi which is clear if you spell it right.
R=(0.75v/pi)^1/3
solve for v
.75=3/4
r=(3/4v/pi)
r^3=3/4v/pi
pi*r^3=3/4v
4/3pi*r^3=v
which is the normal formula for volume of a sphere.

4/3pi*r^3=32pi/3
multiply both sides by 3 and divide by pi
4pi*r^3=32pi
4r^3=32
r^3=8
r=2
