An introduction of pi?
Pi is the ratio of the circumference of a circle to its diameter; it can be calculated as circumference divided by diameter, or circumference/diameter. It is an irrational number which starts 3.14159265358979323846264338327050..., but it is usually approximated to 3.14 or 22/7, though using the [π] button on a calculator makes it easier to enter a fairly accurate value.
Define Pi and a brief history of Pi?
Pi is the number you get by dividing a circle's circumference by its diameter. It is irrational. It is 3.1415926535897. Every generation, people figured out another few didgets of pi.
If the diameter of a circle is 14 cm what is the circumference of the circle?
You need to understand the concept of the number pi. pi is the the number of diameters you can "wrap" around a circle. The number is 3.14... So if you had a circle with a diameter of 1 cm then the circumference would be 3.14 x 1 which equals 3.14 cm Since the diameter is 14 cm the circumference is 3.14 x 14 cm The equation that deals with this is ... circumference = pi x diameter or c=pi x D
What is the circumference of a 4 foot circle?
The circumference of a 4 foot diameter circle may be obtained by multiplying the diameter by pi, which is 3.1416 4 X 3.1416 = 13 (rounded to the nearest whole number)
Why is the circumference alsways 3.14?
The circumference is not always 3.14 , The circumference of a circle is always (pi) times as long as the circle's diameter. (Pi) is a number that can't be exactly written down with digits, that begins with 3.14 . It's defined as the ratio of any circle's circumference to the same circle's diameter. The reason is because that's one of the properties of the thing that we call a "circle".
What is a irrational number equal to the circumference to the diameter of the circle?
The circumference of a circle divided by its diameter is equal to pi which is an irrational number.
Why is the ratio of the circumference and diameter of a circle an irrational number?
Because the circumference of a circle divided by its diameter is equal to pi which is an irrational number.
Is the circumference of a circle considered to be a whole number?
No because the circumference of a circle is pi times diameter and pi is an irrational number
What is an irrational number equal to the ratio of the circumference to the diameter of a circle?
yfsdkv.
Is the circumference of a circle an irrational number?
Yes if the diameter is rational. But it need not be if the diameter is irrational. If the diameter is 3/pi units, for example, then the circumference will be (3/pi)*pi = 3 units.
What number do you get when you divide the circumference of a circle by the diameter of the circle?
This ratio is known as pi which is an irrational number approx = 3.14159265
This is the ratio of a circumference to its diameter?
The circumference of any circle divided by the diameter is pi. Pi is approximately 3.14159....It is an irrational number, never terminates or repeats.
What terms apply to pi?
The circumference of a circle divided by its diameter is the value of pi which is an irrational number.
How is pi measured?
The value of pi is a circle's circumference divided by its diameter and pi is an irrational number.
If a circle is 18 inches in diameter what is the circumference?
The circumference is Pi multiplied by the diameter. In this case, the circumference is 18Pi. We can only approximate this since Pi is an irrational number. The circumference is about 56.55 inches.
How do you find the form of pi?
The circumference of any circle divided by its diameter is the value of pi which is an irrational number.
The diameter of a circle can be divided into the circumference how many times?
The diameter of a circle can be divided into the circumference of a circle pi times. The number pi is about 3.14 in decimal form. Because pi is an irrational number, it cannot be written as a fraction of integers or as a terminal or repeating decimal. The circumference of a circle is said to be pi times the diameter, so by dividing the diameter into the circumference, we would get pi as a quotient.
