Question 3

The cross-section of a parabolic solar concentrator is modeled by the curve with equation

h=23x2+7,x≥0 h = \frac{2}{3}x^2 + 7, \quad x \ge 0 h=32​x2+7,x≥0

where h h\,h is the height in decimetres and x x\,x is the horizontal distance from the vertical axis. The concentrator is capped by a horizontal lid at h=31h = 31h=31. The finite region S S\,S is bounded by the curve, the hhh-axis (x=0x=0x=0), and the lid.

Find the exact area of the region SSS.
