What is circumference of a circle with a diameter of 9?
The circumference is 2 * pi times the radius, or c = 2 * pi * r. The diameter is twice the radius, so c = pi * d, where d is the diameter. Insert mode
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 does sin pie over three equal?
First of all it is NOT 'pie' . 'Pie' is the foodstuff that you eat e,g, apple pie, meat pie. The Mathemtical 'pi' is spelled as 'pi' and is from the Classical Greek alphabet, and represent the small /lower case letter 'p'. To answer your question. Set your calculator in RADIAN Mode. Sin(pi/3) sqrt(3) /2 = 0.8660254.... NB You will have an incorrect answer if your calculator is set in 'DEGREE' Mode.
What is the accurate version of pi?
pi is an irrational number and one characteristic of irrational numbers is that their decimal representation is neither terminating nor recurrent. This is also true for any other base for counting (other than pi itself). Also, pi is a transcendental number and so cannot be represented as a sum of algebraic operation on integers. Although the value of pi has been calculated to an accuracy of over a trillion digits, only 40 digits are required to calculate the circumference of the observable universe to the accuracy of the size of a hydrogen atom!
What is the cubic root of pi squared multiplied by pi?
[pi^(1/3)]^2 * pi = pi^(2/3) * pi = pi^(5/3) The answer is the cubic root of pi to the fifth power.
