Hey guys,
Just a volumes question - I'd appreciate it if you guys could help me (I can't get volumes into my head:
3. The base of a solid is a circle x^2 + y^2 = a^2. Each section of the solid by a plane perpendicular to the x-axis is a square. Find the volume of the solid.
Also find the volume of the solid when instead of the square, each section is a right angles isosceles triangle with its right angle above of the plane, a right angles isosceles triangle with its hypotenuse not on the base and an equilateral triangle.
Thanks heaps guys/
