Find the volume of the solid formed when the region bounded by the curve y - 9 x and the coordinate axes is rotated about the y axis, lam (c) Find the volume of the solid formed when the section of the hyperbola cy - 4 between x and x = 2 is rotated about the y -axis. The diagram shows the graph of y.Use the Trapezoidalrule with 6 subintervals to find the area bounded by the curve the x-axis and the lines x = 3 and x - 3 Question 18 The graph of the function y - v1 + x is shown below. Use the Trapezoidal rule with 5 function values to approximate ( v1 + x x and explain why this approximation underestimates the value of the integral. HI O
