The volume of a cylinder is 1256 meters. The height is 13 meters. Diameter is x. What is the diameter?

  • Math - ,

    Volume of cylinder, 1256 m³
    = πd²h/4
    h=13, π=3.14159, solve for d.

  • Math - ,

    Idg how to to do x squared

  • Math - ,

    d² is the same as d*d, or d multiplied by itself.
    so
    πd²h/4=1256
    multiply by 4 on each side,
    πd²h = 5024
    divide by πh on each side:
    d²=5024/(13π)=123
    d=√(123)=11 metres.
