Why is the charge on a charged sphere distributed uniformly over its surface

As we know that all conductors are equipotential so we can say that all points lie on the surface of conductors will be at same potential.

So here we can say that

now we will multiply numerator and denominator by radius R

so here we will have

now we know that

so we have

since potential is constant so here charge density and radius product will remain constant always

so here on spherical conductor the charge density will remain same at all points

i think its c if i'm wrong

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
