Question #204647

Find the volume of the solid formed by revolving the curve, r=a(1+cosθ), about the initial line.

Expert's answer

"V=\\int\\frac{2}{3} \\pi*r^2 sin A" da

"a=\\theta"

"\\frac{2\\pi}{3}\u222ba^3*(1-cos a)^3 sinA" da

"t=1-cos A"

Sin A "da=dt"

"a=t=0,"

"a=\\pi,"

"t=2"

"Volume=\\frac{8}{3} *\\pi*a^3"
