Asked by Alice
The base of a solid is the unit circle x^2 + y^2 = 4, and its cross-sections perpendicular to the x-axis
are rectangles of height 10. Find its volume.
Here's my work:
A for rectangle=lw
A=10*sq(4-x)
V= the integral from -4 to 4 of sq(4-x^2)*10dx
But that gets me 0, so I know I am wrong. Please help!
