Small Circular: When a clear finish is to be applied, it is essential that you give the surface a final sanding by hand, following the grain of the wood. If an orbital electric sander has been used at any stage, small circular scratches, resembling fish scales, will be seen in the final coat.
A temporary barbecue, which can be dismantled for storage during the winter, can be made by stacking bricks dry, without mortar. Not only is the unit inexpensive and easy to construct in a matter of a few hours, but it is also a very efficient structure: the honeycomb bonding arrangement used to raise the walls ensures a plentiful supply of air to the charcoal for good combustion.
The barbecue can be built in a circular, triangular, square or hexagonal shape, as preferred. A basic circular unit will use about 100 bricks; other shapes need more.
Circular graphs are often used in the presentation of budgets, where the total budget is depicted as a complete circle (or pie) and the various components as sectors (or slices). The sizes of the sectors are proportional to the percent of the total budget of the proposed expenditures. The accompanying illustration of a circular graph gives an analysis of the U. S. budget for the fiscal year 1970. If the total budget is $T, and a category uses $C, then the angle of the sector assigned to the category is (C/T) 360°. |
