Part A: Find the area of R. Part B: The region R is the base of a solid. For eaoh y, where {J 5 y 5 4, the cross section of the solid taken perpendicular to the yaxis is a rectangle whose base lies in R and whose height is 3v. Write, but do not evaluate an expression that gives the volume of the solid. Part 0: Write an expression that oan be used to calculate the total length of the curve on the domain [0, 1G] and nd the length. Part D: Rewrite the curve x] = x2 in terms of y and write the denite integral that can be used to determine the length of the curve fly). 3. Let R be the region in the rst quadrant bounded by the graph of y = x2, the xaxis. and the line x = 3. Part A: Find the area of the region R. Part E: Find the value of h suoh that the vertical line x = h divides the region R into two regions of equal area. 4. Let R be the region bounded by the graph of v = x2 and the line y = 9. Part A: Find the volume of the solid generated when R is revolved about the xaxis. Part B: There exists a number k, k
