Given a region R enclosed by the curves y = 1 + sin y = 4- (x - 2)2 and r = 2 4 as shown below. Set up (and do not simplify) the (sum of) definite integral(s) equal to the following: (2, 4) 1. Arc length of the curve y = 4 - ( (x-2)^2/ 4) bordering the region R 2. Area of R using horizontal rectangles R 3. Volume of the solid generated when R is revolved about the line y = 4 using the (2, 2 ) method of washers (-2, 0)
