(1) the given curve is rotated about the y-axis. find the area of the resulting surface. y = 5 − x2, 0 ≤ x ≤ 2(2) the given curve is rotated about the y-axis. find the area of the resulting surface. y = (1/4)x2-(1/2)lnx 2 ≤ x ≤ 4

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
