Where was pi found?
The value of pi is found by dividing the circumference of a circle by its diameter and pi is an irrational number which means it can not be expressed as a fraction.
How do you find the diameter when given the circumference?
Since circumference is found by multiplying pi by the diameter of the circle, the diameter can by found using the inverse operation. diameter = circumference/pi
What is the diameter of a circle with a circumference of 4.5 inches?
The diameter of a circle is found by dividing the circumference by pi (π). So, if the circumference of the circle is 4.5 inches, then the diameter would be 4.5 inches divided by pi (approximately 3.14), which is approximately 1.43 inches.
How was the number pie created?
By dividing the circumference of a circle by its diameter.
How do you find the surface area when given a circumference?
For a circle the diameter can be found by dividing the circumference by pi. Once the diameter is found by squaring the radius multiplied by pi. For a cylinder follow the previous method and multiply the answer by two. Multiply the circumference of the circle by the cylinder height. Add the two answers together.
