What is the exact values of sin 2 pi?
2*pi is one complete revolution, i.e. 360 degrees. Sin of 2*pi = sin 360º = 0
Why is pi called pi?
It's a Greek letter. Greek letters are often used to express constants (mathematical values that don't change).
What is the Circumference if the diameter is 7.2?
Circumference of circle: 7.2*pi units or 7.2 * 3.14159265 = 22.6194671 with rounded values for pi and the resulting circumference.
Who was it that gave the greek symbol pi?
That was William Jones, from England, in 1705
What is the equation for decibels solved for intensity?
10log10 (p1 /p0 ) where the pi are power values.
What mathmetition gave pi its symbol?
i think it was albert Einstein gave pi its symbol but im not sure.
How many place values in pi?
Pi cannot be expressed exactly as any fraction (including as a fraction of powers of 10, which is what a decimal fraction is). There are an infinite number of place values in the number 'pi'.
How many place values for pi?
infinite number of digits after the decimal point -- pi does not have a finite value.
Given that Pi is infinite would not some long series of it have to repeat now and then?
There are no repeating strings of values in pi.
Why did pi come from tau?
Because pi = 0.5*tau
Who gave pi its name in 1706?
William Jones
In trigonometry what are three values that are not defined?
Cosecant of k*pi radians Secant of 0.5*(2k+1)*pi radiansCotangent of k*pi radianswhere k is an integer.
What is the exact values of sin 2 pi?
2*pi is one complete revolution, i.e. 360 degrees. Sin of 2*pi = sin 360º = 0
How is the perimeter and area of a circle related?
They both use pi to determine their values
What other approximate values for Pi have been used and who discovered them?
Every person who has ever used the "value" of pi in a calculation has used an approximation.
How do you find the radius of a circle if you no the area?
You know: Area = (pi)r2 So, plug in your known values for the area and pi, then solve for r.
What is the circumference of a circle if the radius is 48?
Just use 2 x (pi) x radius (pi) values is 22/7 or 3.142
