The largest diameter is 5 inches; therefore the diameter is 5 x pi.
A circle which is a plane figure, when drawn on a paper has 1 side.
Area is the space or room inside a circle and circumference is like the perimeter or the distance around a circle. In terms of pepperoni pizza, area is the cheesey pepperoni and circumference is the crust. On a plate, area is were you can place food and circumference is the edge.
pie times diameter is the circumference of a circle. a sphere is a 3-dimensional object and you dont take the circumference but rather you take the surface area. the circumference is to measure the total outside distance around the circle. the surface area is the measure the total outside distance around the sphere. remember a sphere is like a ball that is rounded. a circle is just a circle and can only be 2-dimensional.. like on paper
Circumfrence is the perimeter of a circle, the line that makes a circle looks like a circle Imagine a perfect circle drawn on a piece of paper. Take the length of the line of the circle (by line I mean the part that is actually drawn on the piece of paper the ring) and there, you have the circumfrence. The circumfrence is exactly π times the size of the diameter (if you don't know what those two things are ignore this)
Let the side of square be of length '2a' For the largest circle carved out of the square sheet, radius will be 'a' and hence the required area of circle = PI(a2)
If you were to see it drawn on paper, you would be seized by the unmistakable impression that it bears an uncanny resemblance to a circle inside a right triangle.
Basically, perimeter and circumference mean the same thing. They are the measurement of a boundary, be it a large field or a small circle drawn on a piece of paper. Usually, the measurement is either in yards, feet and inches (showing my age here!) or, nowadays, due to metrification, in metres and centimetres.
A=346.1850 cm2
Well, this is the constant Pi. Pi is equal to the ratio of any circle's circumference to its diameter. In simpler terms: Take any sized circle (go on, draw one on paper) and measure how long a piece of string it takes to wrap it once around the circle. This is the circumference of the circle. Now measure the longest distance you can measure in the circle, so that would be from one side to the other side of the circle, over the middle bit, and that value is the diameter. Now take a calculator and divide the circumference by the diameter and voila, you should see a number equal to 3.1415 Go to wiki: http://en.wikipedia.org/wiki/Pi
Both. ANY 2-dimensional shape ... that is, a shape drawn in a plane, or on a piece of paper ... has only one surface.
some one decided to draw a piece of paper on the paper
To make a circle using a compass and a ruler, first place the compass point on the paper where you want the center of the circle to be. Adjust the compass width to the desired radius of the circle. Keeping the compass width the same, draw a complete circle by rotating the compass around the center point. Use a ruler to ensure the circle is drawn accurately and smoothly.
