Who discovered the formula for the circumference of a circle?
Archimedes created the formula for measuring the circumference of a circle he used many-sided polygons, both inside and out to approximate it.
Why is Pi used to calculate circumference and area of circles?
pi is an irrational number at 3.141592.... ( recur to infinity and decimals in no regular order. Let me tell you a story!!!! It was found by the 'Ancient Civilisations' that when a donkey is used to drive up water from well, it was tethered to a rope/halter, the radius. It walked round the well head tied to the halter. in a big circle, the circumference. It was found by the ancients, that twice the radius, the diamter, has a direct proportion to the circumference. It didn't how big/small the circumference was, compared to the radius/diameter the proportion always remained the same at 3.141592.... (pi). So the ancints constructed an equation. C is directly proportional to diameter ,d, This proportion is always constant hence a 'k' for constancy is inserted. C = kd or k = C/d This constant 'k' was given the name 'pi', which is the lower case Classical Greek letter 'p'. and stands for proportion. So ther you have it!!!!!
What is a circumference used for?
To calculate the number of times a diameter can go around the circle
What does the radius of each circle represent in science?
In science, the radius of a circle typically represents the distance from the center of the circle to any point on its circumference. This can be used to calculate various properties such as area, circumference, and relationships between different geometric shapes.
Plzzz HELP ME!What is the circumference of a circle with a diameter of 24 centimeter?
The formula used to calculate circle circumference is C = π · ø C = Circle circumference π = Pi = 3.14159… ø = Circle diameter C= π x 24 C= 75.3982237 inches
How do you get circumference?
Radius of circle times 2, multiply that by pi (3.14 for easyish reckoning), and that's the circumference of a circle. The circumference of an object is the distance around the outside or perimeter. Different formulae are used to calculate this depending on the shape.
What is a circumference used?
The circumference is the measurement around a circle
What two numbers are divided to calculate pi?
Pi (π) is calculated as the ratio of a circle's circumference to its diameter. Therefore, the two numbers used to calculate pi are the circumference of the circle and its diameter. This relationship holds true for all circles, making pi a constant approximately equal to 3.14159.
What do people use pi for?
Since pi is the ratio of the circumference of any circle to its diameter, it comes up any time a radius or diameter is used to calculate most other characteristics of a circle or a sphere, such as circumference, area, surface area or volume, or whenever any of those characteristics are used to calculate a radius or diameter.
What is the mathematical relationship between the circumference of a circle and its diameter?
The mathematical relationship between the circumference of a circle and its diameter is given by the formula C = π * d, where C represents the circumference, d represents the diameter, and π is a constant approximately equal to 3.14159. This formula shows that the circumference is equal to π times the diameter of the circle. This relationship is fundamental in geometry and is used to calculate the circumference of a circle when the diameter is known.
what does one diameter measure?
One diameter measures the distance across a circle, passing through its center and connecting two points on its circumference. It is the longest distance across the circle and is twice the length of the radius. The diameter is a key measurement in geometry and is used to calculate the area and circumference of a circle.
