It is pi*r2*h = 1571 cubic inches, approx.

Area = 14in x 20in = 280in2 Area = 10in x 12in = 120in2

A = 314.16 in2

the chord is 4in long

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.

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.

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!

The volume of your shape is found by multiplying all three dimensions together. 20in x 12in x 10in = 2400in = 200feet
