FRQ 1 A graphing calculator is required for the following problem. [0. 10) Letx) = log(x2 + 1), 90:) = 10 x2, and R be the region bounded by the graphs offand g, as shown above. a) Find the area of the region. b) Region R is the base ofa solid. For this solid, each cross section perpendicular to the x-axis is an isosceles right triangle with a leg in R. Find the volume of the solid. c) Find the volume of the solid generated when R is revolved about the horizontal line y = 10
