Math 1152 Written Homework 1 - Page 5 Spring 2022 3. [6 pts] The region R is bounded by x = V9 y2 and x = 0. o Revolving R about the y-axis produces a solid 51. o R is also the base of a solid 52. Cross-sections through 52 taken parallel to the y-axis are semicircles. Let V1 be the volume of $1 and let V2 be the volume of 52. Use geometric reasoning (not computations) to find a constant a so V1 2 a- V2 and explain your answer using words and pictures
