Hi!

I have a few problems with 'Solve' function.
I'm trying to solve the following equation:
Solve[(4 \[Pi] ((A^3 R^3)/3 + (A^5 R^5)/5))/A^3 - 1 == 0, R]

and I get the result in this form:
{{R -> Root[-15 + 20 \[Pi] #1^3 + 12 A^2 \[Pi] #1^5 &, 1]}, {R ->
Root[-15 + 20 \[Pi] #1^3 + 12 A^2 \[Pi] #1^5 &, 2]}, {R ->
Root[-15 + 20 \[Pi] #1^3 + 12 A^2 \[Pi] #1^5 &, 3]}, {R ->
Root[-15 + 20 \[Pi] #1^3 + 12 A^2 \[Pi] #1^5 &, 4]}, {R ->
Root[-15 + 20 \[Pi] #1^3 + 12 A^2 \[Pi] #1^5 &, 5]}}

Is it possible to rewrite the above explicitly (without #) - to have R as function of A?

thanks
