It is pi*r2*h = 1571 cubic inches, approx.
Area = 14in x 20in = 280in2 Area = 10in x 12in = 120in2
A = 314.16 in2
Surface area excluding the bases: 20*pi*5 = 100*pi square inches
It would depend on what kind of placemats. The general rectangular placemats are approximately 12in x 18in, but the 14in x 20in hold an entire place setting, and is usually the most commonly-used. Then there are small placemats that hold only a dinner plate, and are about 12in in diameter (if circular) or length.
The longest water hose was made in Germany. It is painted with red polyurethane enamel. It measures 410ft. long and 20in. in diameter. It connects to a faucet that is 35ft. 5in. in height.
the chord is 4in long
2*(30 * 20 + 20 * 14 + 14 * 30) = 2*(600 + 280 + 420) = 2*1300 = 2600 sq inches.
An English saddle is 2" more than a western saddle. For example: 14in western=16in English 16in western=18in English 18in western= 20in English
The circumference of a circle (the distance around the perimeter) is calculated by mulitplying a constant value called Pi (which equals 3.14 and is true for all circles), times the circle's diameter (distance across the center).Therefore, to answer your question, C = Pi x D, or 3.14 x 20in, or 62.8 inches.
20in = 50.8cm @2.54cm per inch.
area of triangle: area equals base times height devided by two! a=bxh/2 a=40in b=20in THE ANSWER IS 4in as the height!
