we are given
Since, we have to solve for b
so, we will isolate b ony one side
so, we will add 60 on both sides
so,
Answer:
Maureen should have added 60 to both sides.
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.
