  1. A parabola x = y² with 0 ≤ x ≤ 1 is shown in the figure. The volume of the solid of rotation obtained by rotating the shaded area by 360° around the x-axis is
    1. π/2
    2. π/4
    3. π
Correct Option: B


Here, volume of solid of rotation by rotating shaded area by 360° around x-axis is,
V = 10πy²dx

V = 10 πx dx =
πx²
² =
π
