When was pi first being used approximated?
the great pyramids did this.
Pi is used to find the area and perimeter of a circle and the volume of a sphere, cylinder, and cone. Pi=3.14159265358979323846264338327950288419716939937510582097494459230781640628620899862803482534211706798214808651328230664709384460955058223172535940812848111745028410270193852110555964462294895493038196... That was 200 decimal places of Pi.
William Jones first used the pi symbol (π) in 1706
Pi (3.141...) is used for circles, and circles only. You use it to find the area and circumfrence.
Usually a circle but its properties can also be applied to spheres
Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)
Primarily circles and spheres.
Because the circumference of a circle divided by its diameter is equal to pi.
A circle is different from another shape because of the following reasons:- It is a perfectly rounded shape It has a circumference It has a diameter It has a radius It has chords It has sectors It has segments It has infinite lines of symmetry Its circumference divided by its diameter is the value of pi Its area is: pi times radius squared Its circumference is: 2*pi*radius or diameter*pi
The only shape that can do that is a circle.Circumference = 24.Diameter = 24/piRadius = 12/piArea = pi R2 = 144/pi = 45.837
pi r^2 h is used to determine the volume of a cylinder because when determing the area of a shape you first have to determine the area of the the base of the object and then multiply it by the height. The base of a cylinder is a circle and to find the area of a circle you use pi r^2 and hence the reason why pi r^2 is used to find the volume of the cylinder.
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
Pi was first used by the Babylonians and Egyptians.
The height of the can in terms of Pi is: about 3.85picm
well pi is used to find the area of a circle A=pi x the radius squared
