What are 3 uses of pi?
Finding the area of a circle: pi*radius2 Finding the circumference of a circle: 2*pi*radius or diameter*pi Finding the surface area of a sphere: 4*pi*radius2
What formulas use Pi in the equation?
a formula that uses pi is the circumference and area of a circle and every polyhedron that has a circle
What is the formula for area using pi?
It depends on the shape you need the area of, the most common one is for a circle. That is Area=Diameter x Pi
Square footage for round shape?
or where is the area, and is the radius. (Pi) = 3.14159 should be close enought for most calculations. A=Pi * r * r where is the area, and is the radius. (Pi) = 3.14159 should be close enought for most calculations.
How and when do you use pi in school?
Some of its uses and applications are as follows:- Circumference of a circle: 2*pi*radius or diameter*pi Area of a circle: pi*radius2 Volume of a sphere: 4/3*pi*radius3 Surface area of a sphere: 4*pi*radius2 Volume of a cone: 1/3*pi*radius2*height Curved surface area of a cone: pi*radius*slant length Volume of a cylinder: pi*radius2*height Entire surface area of a cylinder: (2*pi*radius2)+(diameter*pi*height) Pi is the value of a circle's circumference divided by its diameter Pi is the 16th letter of the Greek alpabet
How do you get from diameter to area of a circle?
The area of a circle is its diameter times the value of PI. In most cases you can safely use the 3.14159 for the value of PI
What is the area of a circle with a radius 2.1 centimeters?
the area of a circle is represented by the following equation; A=pi*R2 where A is area, pi is the number pi (3.1415926.......for most high school maths, 3.14 is suitable) and R is the radius. So, square your radius, and multiply it by pi.
How do you calculate pipe area for pipe insulation jobs?
THE DIAMETER OF THE OUTSIDE OF THE PIPE TIMES PI TIMES THE LENGTH OF THE PIPE or D x Pi x L = A
What you the relationship of pi and area?
The area of a circle is pi times the square of the radius. Pi has no relationship with the area of a polygon.
How do you calculate circumference and area of pi?
Pi is the number of times the diameter of a circle will fit into the circumference. Pi is not a circle, and does not have a circumference or area. To calculate a circumference USING pi, the circumference is diameter * pi. To find the area using pi, area = pi * radius * radius
What is the formula for finding the surface area using 3.14?
Assuming that 3.14 is pi, then most likely you're looking for the surface area of a circle, which is pi x r2.
What is the area of a circle you the circumference is 12 pi ft?
Circumference = 2 * pi * radius 12 pi ft = 2 pi radius radius of the circle = 6 ft Area = pi *radius2 Area = pi (6)2 Area = 36 pi ft2
