What is the circumference of a circle with a diameter of 8 meters?
To determine the circumference of any circle, multiply the diameter by pi. Pi is approximately equal to 3.1416
Why do people use Pi?
people use pi to find the circumference of a circle.
Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
What is the approximate circumference of the circle. Use 3.14 to approximate pi?
If pi=3.14, then the circumference is ( 3.14 times the diameter).
What are the two formulae you can use to find the circumference of a circle?
Circumference of a circle = 2*pi*radius or pi*diameter
How do you get circumference for the circle?
Measure the diameter. Multiply the diameter by Pi, this will give the circumference. Pi is approximately 3.1415927 You can use the Pi symbol on a scientific calculator or use 22/7.
What is the circumference of a circle with radius 11.8 in both terms of pi and to the nearest tenth use 3.14 for pi?
circumference = 2 * pi * radius circumference = 2 * 3.14 * 11.8 circumference = 74.104 Circumference = 2*pi*radius Circumference = 2*3.14*11.8 = 74.104 = 74.1 to the nearest tenth
Why do we use pi?
The ancient civilisations, 4000 years ago, Sumerians, calculated 'pi' to be 3.141592..... The story goes ; A donkey on a tether ( radius) was driven around in a circle (Circumference) to drive water up from a well. They noticed that however, long the tether (radius) was , the correspodning circle(circumference) was always in the same ratio. ; pi = 3.141592..... This can be mathematically expressed as Circumference is directly proportional to the diameter. or 'C' is directly proportional to 'd ' This can be equated with a constant C = k d Algebraically rearranged as k = C/d Whatever the dimensions of a given circle were/are 'k', the constant, was always found to be 3.141592.... Much later after the Sumerians, the Classical Greeks, gave the name 'pi' to this constant. 'pi' being the lower case classical Greek letter 'p' and refers to **P**roportion. Hence 'pi' , today is used as this constant of proportion for circles. 'pi' is an irrational number, which means in casual terms, the decimal digits go to infinity and there is no regular order in the decimal digits. On 'Supa-Dupa' computers' pi' has been calculated to some 50 billion places and still going. NB Remember the circle equations. C = pi d C = 2 pi r ( d = 2r) A(area) = pi r^(2) When learning circle calculations you are probably given pi as 3.14, or .3.1416. or 22/7, but these are only approximate values, and NOT exact values. Hope that helps!!!!!
What do pi have to do with math?
you use pi to calculate the area or circumference of a circle
How is finding the area of a circle similar to finding the circumference of a circle?
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
How do you determine the radius if you know the area and the circumference of a circle?
If circumference(C) is given, then r = C/2(pi) If area(A) is given, then r = (A/pi)1/2
How do you find the circumference of a circle using the radius?
Circumference = 2*pi*radius So the radius = circumference/2*pi
