the perimeter is 3 times as long as the diameter Example: if my diameter is 7 inches long my perimeter is 3 times as much so it is 21 inches long

330.78 ft3

Area = pi*r2A ratio.A = pi*(12)2-------------A = pi*(10)2cancel all like factors144/100= 1.44 times larger==============

The answer depends on the square!

Diameter = 1.5/pi = 0.4774648293 of an inch

no because the radius is half the diameter so it must be multiplied by two in order to find the diameter of that circle which is 4 times 4 equals to 8 so the circle which has a diameter of 5 inches is much to small for a circle with a radius of 4 inches to fit.

A bike is not a circle, so the question doesn't mean much as it's stated. But we'repretty sure that you're referring to one of the bike's wheels.The definition of "diameter" is "double the radius". If double the radius is 24 inches,then the radius is (24/2) = 12 inches.

Circumference of a circle = pi DCircumference of the big one = 12 piCircumference of the small one = 8 piDifference = (12 pi - 8 pi) = (12 - 8) pi = 4 pi = 12.5664 inches (rounded)

By a 21-inch circle I presume you mean that the diameter is 21 inches. So the radius is half as long, 10.5 inches. The formula for the circumference of a circle is 2 pi r, where r is the radius. Pi is about 3.14. That is accurate to 2 decimals, or 3 significant digits all together. I use that approximation because the dimension we are given has 2 significant digits. So the circumference is pi times the diameter; we multiply 3.14 by 21 inches and get 65.94. To 2 significant digits, that is 66 inches. If you meant that the radius was 21 inches, then the circumference would be twice as much, or 132 inches.

Assuming you are talking about a cylinder, all you need to do is calculate the area of the circle and multiply it by the height of the cylinder. The area of a circle is pi*r^2. So with a height h, the volume would be h(pi*12^2) = h * 144pi.
