7 The base of a solid is the region in the say-plane bounded by the curves 3; = 7 E932 and y = 0. Every cross-section of the solid parallel to the :c-axis is a triangle whose height and base are equal. The volume of this solid is: The base of a solid is the region in the my-plane between the the lines 3; = as, y = 593, a: = 3 and a: = 5. Cross-sections of the solid perpendicular to the m-axis (and to the any-plane) are squares. The volume of this solid is: A volume is described as follows: 1. the base is the region bounded by :1: = y2 + 2y | 160 and m = y2 26y | 186; 2. every cross section perpendicular to the yaxis is a semi-circle. Find the volume of this object. Find the average value of f(ac) = ac2 113 + x on the interval [0,2]. fave = Round your answer to 5 decimal places
