It is still equal to pi (3.1416) because when you multiply anything by 1 no matter how many times you multiply it, you end up with that other number.

What is pi times pi divided by pi plus pi minus pi times pi?

the same as pi squared, which is 9.86960440109


What is one third times pi?

One third times pi can be calculated by multiplying 1/3 by the value of pi, which is approximately 3.14159. Therefore, 1/3 times pi equals approximately 1.0472. This can be simplified to the fraction 10472/10000 or the mixed number 1 and 472/10000.


How do you use pi to determine circumference?

Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)


What is the area of a circle radius equal to 1?

The area of a circle is pi times (radius squared) Thus if radius is one inch then area is (pi) times (1) times (1) = pi = 3.1416 inches squared


How many radians are 10 revolutions?

20 times pi There are 2 pi radians in one revolution.


How do you find the pi circumference and area of circles?

Area=pi times radius squared Circumference=pi times diameter or pi times radius times two


What are the two formulas for circumference?

C= 2 times pi and C= pi times diameter C= 2 times pi and C= pi times diameter


Why is circumference equal to 2 times Pi times r?

Circumference = pi times diameter or Circumference= two x pi x radius. Now remember the diameter of a circle is the straight line from one edge of the circle, through the centre to the opposite edge. The straight line from the edge to the centre is the radius, and then from the centre to the opposite edge is another radius. So the diameter is the length of two radii. Algebraically express as d = 2r. So Algebraically C = pi*d Substituting the 'd' for '2r' C = pi2r However in algebra coefficient numbers are expressed to the left. Hence C = 2pir Why 'C' is this expression I would have to go into some 'very heavy' differential calculus. Suffice it to say, the ancients found that the circumference traced by a donkey/mule driving water out of well was directly proportional to the diameter, twice the length of the tether(2 radii). From this they discovered that for however long the the tether and the circumference were. they had a constant of proportion C directly related to diameter. This is equated to C = kd And k = C/d , which was founf to be 3.141592..... which now call 'pi'. for any sized circle. So today in school you learn C = pi d or C = 2 pi r And for circular area(A) A = pi r^(2) The 'pi' youare given in school is proabably 3.14 , 3.1416 or 22/7 . However, these values are Approximatons, because 'pi' is an irrational number. Hope that helps!!!!!!

How do you calculate the circumference if you know the diameter?

Circumference is equal to 2 times pi (3.1416) times one half of the diameter (the radius). So, if the diameter is 2 cm, then the circumference would be the product of (2) times (3.1416) times (1), or 6.2832 cm. Circumference is equal to diameter times Pi. c = Pi * d diameter times pi
