What geometric shape helped the Egyptians to come up with pi?
the great pyramids did this.
What 3 things in math is pi used to find?
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.
How can pi be used?
Pi (3.141...) is used for circles, and circles only. You use it to find the area and circumfrence.
Who first used the symbol of pi?
William Jones first used the pi symbol (π) in 1706
Pi number can ONLY be used for which shape?
Usually a circle but its properties can also be applied to spheres
How do you work out the area if given the circumference?
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)
Which shape is pi associated with?
Primarily circles and spheres.
Why you use pi in circular shape's formula?
Because the circumference of a circle divided by its diameter is equal to pi.
How is a circle different from a other shape?
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
What shape is this perimiter of 24 and the area is greater then 36?
The only shape that can do that is a circle.Circumference = 24.Diameter = 24/piRadius = 12/piArea = pi R2 = 144/pi = 45.837
Why is the volume pi r h for a cylinder?
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 blank of a circle?
Pi can be used to calculate the area of a circle Pi can be used to calculate the circumference of a circle
Where was pi first used?
Pi was first used by the Babylonians and Egyptians.
A soup can is in a shape of a cylinder The can has a volume of 342cm3 and a diameter of 6cm What is the height of the can in terms of Pi?
The height of the can in terms of Pi is: about 3.85picm
What is shape factor for sphere?
The shape factor for a sphere is a dimensionless quantity that characterizes its geometry in relation to its volume and surface area. It is defined as the ratio of the surface area of the sphere to the square of its radius, which is given by the formula ( \text{Shape Factor} = \frac{4\pi r^2}{(2r)^2} = \frac{4\pi r^2}{4r^2} = \pi ). This indicates that the shape factor for a sphere is constant and equal to ( \pi ), reflecting its uniformity in all directions.
What is the math subject that the pi is mainly used in?
well pi is used to find the area of a circle A=pi x the radius squared
