Question
a. Calculate the volume of the solid of revolution created by rotating the curve y = 2+4 exp(-2 x) about the x-axis, for x between 1 and 4. Volume : b. The equation of a circle of radius r, centered at the origin (0,0), is given by r² = x² + y² • Rearrange this equation to find a formula for y in terms of x and r. (Take the positive root.) Equation: y = o What solid of revolution is swept out if this curve is rotated around the x axis, and x is allowed to vary between -r and r? (You do not need to enter this answer into WebAssign.) O Suppose we wanted to set up the following integral so that V gives the volume of a sphere of radius r = [²₁ f(x) dx a V = What would a, b and f(x) be? a = b = f(x) = = (WebAssign note: remember that you enter π as pi) o Carry out the integration, and calculate the value of V in terms of r. V =
