Best Answer

A circle's circumference when divided by its diameter is the value of pi which is an irrational number because it can't be exactly expressed as a fraction.

Relation of pie With circle?

The value of pi for any circle is the circle's circumference divided by its diameter.


How is pi in relation to a circle?

Pi is related to the area and the circumference of the circle. The area is Pi multiplied by the radius of the circle squared and the circumference is Pi times the diameter of the circle. if you're wondering how it works, pi is the area of a circle with radius of 1 (unit), and the circumference of a circle with a radius of ½ (unit).


What is the difference between circle and Pi?

This is PI, pi = 3.14159265...... A circle is the round thing, like your pies! The area of a circle is measured using (Pi)(radius to the power of 2). Circumfrance of a circle is (Pi)(Diameter of circle).


What is relation between pie and circle?

It is pi, a letter in the Greek alphabet, and pronounced like pie. This infinite value, usually expressed as 3.14 or sometimes more accurately as 3.1416 is the ratio of the diameter (distance across) a circle, and the circumference (distance around) a circle. The diameter times pi equals the circumference, and the circumference divided by pi gives the diameter. Also, the radius (half the diameter) times itself and then multiplied by pi gives the area inside a circle. The value of pi is the same regardless of the size of a circle.


What is Pi and who invented or discovered Pi?

Pi is the relationship between the diameter and the circumference of a circle.


What is the relationship between and pi?

pi X diameter = circumference of the circle.


What is the relationship between pi and circles?

The circumference of a circle is pi times the diameter. The area of a circle is pi times the radius squared.


How is pi related to the sun?

Pi is the ratio between the circumference of a circle and its diameter. The Sun is also round - like a circle.


What is the diameter of a circle with the area of 25?

The functional relation between the diameter d and the area a is a = (pi)(d/2)2. Therefore, (pi)d2 = 22(25) = 100; d = sq rt (100/pi) = 5.6 units, to the justified number of significant digits.


What is pi in an explanatory form not the number form?

pi is the ratio between the circumference of a circle and it's diameter. If you take the circumference of any circle, and divide it by that same circle's diameter, the resulting number will be pi.

Why is pi always 3.14?

Because pi is a constant. It is the ratio between the circumference and diameter of any circle (assuming it is a perfect circle).


How did pi come about?

It was inititially recognised as the ratio between the radius and circumference of a perfect circle. The radius times "Pi" equals the circumference of a perfect circle.


What is the relationship between the circumference of a circle and its diameter?

The circumference of a circle is equal to pi times its diameter. Another way to say this is that for any circle, circumference divided by diameter will always have pi as the answer, regardless of the size of the circle.


What is pi and how does it relate to the circumfrance?

The number pi is the ratio of the circumference and the diameter of a circle. In Euclidian ("flat") geometry, this ratio is the same for all circles. The number pi is approximately 3.1416. It also has many other uses in mathematics and physics, not all of which have an obvious relation to a circle or sphere.


What a relationship between pi and circle?

Pi ( 3.142 approx.) is the amount of times the diameter of a circle can be measured along the circumference of a circle. We know that Pi multiplied by the diameter of the circle is equal to it circumference. So we write C=PiD This means, as it says above, that a certain number of "Pi's" will be equal to the circumference.


What is theRelationship between the diameter of a circle and the area of the same circle?

The area of a circle is given by the formula pi*r^2, where r is the radius of the circle. Diameter = 2*r, so: area = pi*(d/2)^2 = (1/4)*pi*d^2


What is the realtionship between the diameter and circumference of a circle?

The circumference of any circle is its diameter multiplied by (pi).


What is the relationship between pi and diameter?

In any circle, the product of pi and the diameter will be the circumference. That is because pi is the ratio of the diameter of a circle to its circumference. Here is the equation: c = pi x d


What fraction of the area of a circle of radius 5 lies between concentric circles of radius 3 and 4?

The area of a circle with radius 5 is 25 pi. Concentric circles with radius 3 and 4 have areas of 9 pi and 16 pi. The concentric circle with radius four consumes the circle with radius 3. 25 pi minus 16 pi leaves 9 pi of the circle with radius 5 left over. 16 pi is slightly over three-fifths of the circle with radius 5.
