Fill in first box and then any one of the next four boxes. Also fill in the 1st box of last row if you want to compute tanker. Then click the button. The second row is for circular segment (cols 2&3) and circular sector (cols 4&5). The 3rd row is data for spherical cap and spherical sector. The last row is for tanker surface area and volume.
