the volume of a cylinder is 88 m. If the radius of the cylinder is quadrupled, what will be the volume of the new cylinder in cubic meters?

  • geometry -

    volume = base area * height
    the height did not change
    the radius, r is now 4 r
    so the radius squared(in A=pi r^2) is 16 times
    so the volume is 16 times
    16 * 88 m^3
