Volumes of Solids of Revolution (6.2 & 6.3) • Dynamic Illustration #1 (discs) • Dynamic Illustration #2 (washer) • Dynamic Illustration #3 (shell) • Dynamic Illustration #4 (cross section I) (cross section II) MAT 146
Consider the first-quadrant region R with borders y = sin(x) y = 0 and x = π/2 Sketch region R on the xy-plane. Calculate the exact area of R. Show evidence to support your solution. Set up, but do not calculate, a definite integral to represent the volume of the solid created when R is revolved around the y-axis. MAT 146
