What does pi times pi equal?
3.14 x 3.14 = 9.8596
How can you find the circumference of a circle with radius or diameter?
The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
What does pie times 50 equal?
If you mean pi then: 50 times pi is about 157 to the nearest whole number
What does 10 pi times 3.14 equal?
98.596
Is a power a whole number?
Not necessarily. i times pi is not a whole number, and yet e to the power of i times pi is equal to -1.
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!!!!!!
What is 12.8 times pi?
When you multiply 12.8 times pi the exact answer is12.8 Pi, but you can round off the answer to40.192because pi is about equal to 3.14.
What does pi times pi equal?
3.14 x 3.14 = 9.8596
How can you find the circumference of a circle with radius or diameter?
The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
What is pi times 5 equal?
15.7
What does pie times 50 equal?
If you mean pi then: 50 times pi is about 157 to the nearest whole number
Does circumference times diameter equal pi?
No; circumference divided by diameter equals pi.
What does 10 pi times 3.14 equal?
98.596
Why is the circumference of a circle diameter times pi or 2 radius times pi?
Because 2 times the radius is equal to the diameter of the circle
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
Is a power a whole number?
Not necessarily. i times pi is not a whole number, and yet e to the power of i times pi is equal to -1.
What is the area of the circle if the radius is 5?
The area of a circle is equal to pi times the radius squared. So in your case it would be 5 squared, (25) times pi which is equal to ~78.5
