Unformatted text preview: a, b ], then the area between the graphs of f and g is given by Area = A B f ( x ) g ( x ) dx . o When f ( x ) = x + 1 , g ( x ) = 1 2 x , therefore, the value of 4 ( x + 1) + 2 1 x dx o is the area of the shaded region 5. V = 1 3 6. V = 1 3 Explanation: The volume of the solid of revolution obtained by rotating the graph of y = f ( x ) on [ a, b ] about the xaxis is given by volume = A B f ( x ) 2 dx . When f ( x ) = x 2 , a = 2 , b = 3 , 6 therefore, 4 . V = 2 3 x 4 2 dx . 2 Consequently, 2 4 6 V = x 4 2 3 = 3 2 . keywords: AreaBetween, AreaBetweenExam, 003 10.0 points Find the volume, V , of the solid obtained by rotating the region bounded by y = x 2 , x = 2 , x = 3 , y =...
