Question

if the value of the sphere is numerically equal to its surface area then find its diameter

Answer 1

I think the question is:

If the volume of the sphere is numerically equal to its surface area then find its diameter..

Since V= TSA

=) 4/3 * pi * r^3 = 4 * pi * r^2

=) r = 3

Hence d = 2×r
= 6.
