الصفحة 679 - MULTIPLY the radius, or half the diameter, by half the arc of the sector, for the area. Or, multiply the whole diameter by the whole arc of the sector, and take -f .of the product.
الصفحة 679 - Find also the area of the triangle, formed by the chord of the segment and the two radii of the sector. Then...
الصفحة 680 - Multiply the sum of the two parallel sides by the perpendicular distance between them, and half the product will be the area.
الصفحة 681 - Sides 5 6 7 8 9 10 To find the area of a polygon: Multiply the sum of the sides (perimeter of the polygon) by the perpendicular dropped from its center to one of its sides, and half the product will be the area. This rule applies to all regular polygons. FIGURE 3.57 Polygons.
