## Homework Statement

The plates of a spherical capacitor have radii 31.0 mm and 43.0 mm.

What must be the plate area of a parallel-plate capacitor with the same plate separation and capacitance of 12.4pF

## Homework Equations

C=(epsilon*A)/d

## The Attempt at a Solution

12.4*10^-12=(8.85*10^-12*A)/(.012m)

so A=.0168m^2=1.68cm^2, which is incorrect?
