Homework Statement
Rotate the region bound by the given curve by about the x and y axis. Find the volume through the cylindrical method.
x^2 + (y-1)^2 = 1
Homework Equations
Cylindrical method: ∫2∏xf(x)dx
Slice Method: ∫A(x)dx
The Attempt at a Solution
x^2 + (y-1)^2 = 1
x = √(2y - y^2)
∫2∏x(√(1-x^2)+1)dx from -1 to 1
But this simplifies to 0... What am I doing wrong?
