The volume of a sphere with radius "r" is given by: V = 4*π*r³/3 so: r = (3V/(4π))^(1/3) The surface area of a sphere with radius "r" is given by: A = 4π*r² You want to know the area given the volume...

AC = 2. See below for explanation. Notice that there are two similar triangles, ABC and EBD. The area of EBD is twice that of ABC, since the trapezoid area is equal to that of triangle ABC. But, the square...

I've spent some time researching this and I'm pretty sure this is right: V = ∫E dr = ∫ (λ / 2πrε₀) dr = (λ / 2πε₀)*ln(R/r) = 4800 V The only question I have is "what is R" -- in other...
