What is the diameter of a circle if it's circumference is 4 inches?
Well, honey, if the circumference of a circle is 4 inches, then the diameter would be about 1.27 inches. You just divide the circumference by pi (3.14) to get the diameter. Math can be a piece of cake if you just remember the formulas!

What is the circumference of a 50 cent piece?
The circumference of a standard U.S. 50 cent piece, also known as a half dollar, is approximately 11.34 centimeters (or about 4.5 inches). The coin has a diameter of 3.1 centimeters (1.2 inches), and the circumference can be calculated using the formula (C = \pi \times d), where (d) is the diameter.
How do you discover pi?
First draw a circle using a compass. Now, use a piece of string to help measure the circumference of the circle. Now measure the diameter of the circle. To discover Pi divide the circumference by the diameter.

How do you measure the diameter of a metal pole?
You could use a pair of calipers. Alternatively, measure its circumference using a piece of string and divide the measure by pi.
How long would you cut a piece of cable to create a 12 diameter circle?
CIRCUMFERENCE = pi x D = 3.14 x 12 = 37.68 feet
What is the circumference of a paper towel tube?
It depends how big it is. Or, the circumference can be one way of defining how big it is. That is, a tube with circumference 10cm will have a circumference of 10cm. This question belongs to the class of questions characterised by "how long is a piece of string?"
How do you cut a circle into equal sections of small central angle to find the area of circle?
Like cutting up a round cake (each piece starting at the centre) into very thin pieces. Each piece looks very like a thin triangle. Now arrange them next to each other alternately with points up and points down. For very thin pieces it looks almost exactly a rectangle, with the short side equalling the radius, and the 2 long sides totalling the original circumference. So the length of the rectangle is half the circumference. So the area must be RxC/2. Now pi is defined by "circumference of a circle = pi x diameter" so use that in the above area formula to get area = R x pi x diameter/2. But diameter/2 is radius. So the area is pi x R x R = pi x R2.
What is a piece of the circumference of a circle called?
Part of the circumference of a circle is an arc.
How do you spell pieces?
The plural form of the noun 'piece' is spelled pieces, just as in your question.
