To determine how much can be placed on a circular serving tray with a diameter of 18 inches, first calculate the area of the tray. The radius is half the diameter, so it's 9 inches. The area ( A ) can be calculated using the formula ( A = \pi r^2 ), which gives approximately ( A \approx 254.47 ) square inches. This area represents the maximum surface space available for placing items on the tray.
The surface of a circle is given by the formula d2pi/4, so for our 44 inch diameter table, that gives 484pi square inches, which is aproximately 1520.531 square inches.
If the ratio of the lengths is a:b then the areas are in the ratio of the square of these, namely a2:b2The lengths are in the ratio 8:12 ⇒ 2:3Therefore the areas are in the ratio 22:32 ⇒ 4:9So the area of the larger table is 9/4 = 21/4 = 2.25 times the area of the smaller table.
