What is the formula for the circumference of a sphere?
C = 2(pi) r circumference of a sphere = 2*pi*radius or pi*diameter (Any circular circumference is the same for a perfect sphere.)
Why is pi important in layman term?
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
What is the formula for finding circumferencE when only diameter is given?
Circumference of a circle = (pi) x (diameter)
What is the formula for finding the volume of a sphere?
Volume of a sphere = 4/3*pi*radius3 and measured in cubic units
Given a sphere with radius r the formula 4r2 gives?
If you mean 4*pi*r^2 then it is the formula for finding the surface area of a sphere
What is the formula for finding the radius of sphere?
1/2 diameter or the circumference/pi/2
What is the formula for the circumference of a sphere?
C = 2(pi) r circumference of a sphere = 2*pi*radius or pi*diameter (Any circular circumference is the same for a perfect sphere.)
What is the formula for finding perimeter of sphere?
A sphere does not have a perimeter. It can have a diameter a circumference or a surface area (or volume but that isn't discussed here.The diameter of a sphere is two times the radius (r): so the formula would be2r...or...2 x rThe circumference (C) of a sphere is equal to 6.2832 times the Radius, where 6.2832 is twice Pi (): so the formula would beC = 2r...or...C = 2 x x rThe area of a sphere is equal to the Square of the Radius of the sphere multiplied by 12.566 (4 times ): so the formula would be4 * * R * R
Why is pi important in layman term?
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
Formula for finding the circumference of cone?
There is no circumference of a cone, but, we only do the circumference of the circle. the formula for the circle is pi times D. D= Diameter
What is the formula of finding the radius of a sphere?
diameter/2
What is the formula for finding the volume of sphere?
The volume for a sphere is: 4πr3 3 the π is pie (3.14)
What is the formula for finding circumferencE when only diameter is given?
Circumference of a circle = (pi) x (diameter)
What is the formula of finding the circumference of the pipe?
diameter times 3.14159
What are everyday uses for pi?
Some of many examples are:- Finding the circumference of a circle Finding the area of a circle Finding the surface area of a sphere Finding the volume of a sphere Finding the surface area of a cylinder Finding the volume of a cylinder Finding the volume of a cone Finding the surface area of a cone
What is the formula for finding the radius of a circle when you have the circumference?
Divide the circumference by 2*pi because 2*pi*radius = circumference
What is pi used for in geometry?
Some of the many applications that pi is used in geometry are as follows:- Finding the area of a circle Finding the circumference of a circle Finding the volume of a sphere Finding the surface area of a sphere Finding the surface area and volume of a cylinder Finding the volume of a cone
