Homework Statement
x^2 + (y - 2)^2 = 1
The hint given by the question was to split the function into 2
Homework Equations
Surface Area about x axis
The Attempt at a Solution
So i did this.
(y - 2)^2 = 1 - x^2
y = √(1 - x^2) +2 and y = 2 - √(1 - x^2)
The range I calculated
when y= 0; x = - √(-3) and x = √(-3)
I use the formula ∫ 2∏ * (√(1-x^2) + 2)√(1 + x^2/(1 - x^2))dx
Then i got stuck as it became messy
