, you end up with the differentials
. Multiplying both sides by 2 gives
.
Then the integral is
The surface area of a sphere is 4r^2pi, so dividing 100 by 4pi gives a result of 25/pi. Taking the square root and rationalizing the denominator, we have 5sqrt(pi)/pi as the radius of the sphere.
The answer is (-7r-6s)/3s
