Let R denote the region in the plane consisting of all points (x,y) where x ≥ 1 and 0 ≤ y ≤ 2/x. Let S denote the solid formed by rotating R about the x-axis. Observe that S is an unbounded region; that is, it extends indefinitely in the direction of the posi...

The graph of the curve y2=10 x+10 is a parabola, symmetric with respect to the x-axis. Find the area of the surface generated by rotating about the x-axis the part of this curve corresponding to 0 ≤ x ≤ 20.

Math
Because diameter is twice the radius, the radius must be 1/2 of 8 ft. So r=4ft. The circumference is equal to 2*pi*radius. Since pi is =3.14 Thus by comparing the two equations D=2r C=2rpi the only difference is pi so the answer would be F if you assume 3.14 is approximately 3
