Answer: 166 milligrams
Step-by-step explanation:
Given : A certain medicine is given in an amount proportional to a patient's body weight.
A patient weighing 153 pounds requires 249 milligrams of medicine.
Let x be the amount of medicine required by a patient weighing 102 pounds, then we have the following equation:-
Hence, the amount of medicine required by a patient weighing 102 pounds = 166 milligrams.

Presumably you should be doing this using calculus methods, namely computing the surface integral along 
.
But since describes a sphere, we can simply recall that the surface area of a sphere of radius 
is 
.
In calculus terms, we would first find an expression for the surface element, which is given by
So the area of the surface is
as expected.
