Find the volume of the solid of revolution formed by rotating the specified region R about the x axis. Volume Formula Suppose f(x) is continuous and f(x) 0 on a x b, and let R be the region under the curve y = f(x) between x = a and x = b. Then the volume of the solid S formed by rotating R about the x axis is VS = b =S (f(x)); (f(x)) 2dx a R1 is the region under the curve y = x + 1 from x = -1 to x = 2. R2 is the region under the curve y from x = 1 to x = 3. QUESTION 7 VOLUME OF SOLID OF REVOLUTION 5 points Save Answer Find the volume of the solid of revolution formed by rotating the specified region R about the x axis. Volume Formula Suppose f(x) is continuous and f(x) 0 on a x b, and let R be the region under the curve y = f(x) between x = a and x = b. Then the volume of the b solid S formed by rotating R about the x axis is VS = a (f(x)) 2dx R1 is the region under the curve y = x + 1 from x = -1 to x = 2. R2 is the region under the curve y = Vx from x 1 to x = 3.
