Homework Statement
a resistor of a solid sphere of radius R=.75 cm and is made of a material of resistivity[tex]\rho[/tex]=6.8e-8[tex]\Omega[/tex]m. the sphere is sliced on either side vertically so that the horizontal diameter is equal to R. if the current is flowing from left to right what is the objects resistance?

The Attempt at a Solution
well i can appreciate that i need to multiply [tex]\rho[/tex] by a meter amount so
[tex]\int[/tex]of [tex]\Pi[/tex]r^2 of the cut off portion from -r/2 to r/2 would give me an area. to be honest I'm not even sure how to set this integral up.
any help would be greatly appreciated
