Abstract
The article describes calculation of geometric characteristics of plane figures, which outlines are described by cubic spline curves. The authors obtained the exact formula to calculate area and static moments. The formulas allow to define the position of the center of gravity of figures and volumesof bodies formed by rotation of shapes around the axis.
