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
Who discovered the formula for the circumference of a circle?
Archimedes created the formula for measuring the circumference of a circle he used many-sided polygons, both inside and out to approximate it.
What is a circumference used for?
To calculate the number of times a diameter can go around the circle
Why is Pi used to calculate circumference and area of circles?
Because of the radius of the circle
Plzzz HELP ME!What is the circumference of a circle with a diameter of 24 centimeter?
The formula used to calculate circle circumference is C = π · ø C = Circle circumference π = Pi = 3.14159… ø = Circle diameter C= π x 24 C= 75.3982237 inches
How do you get circumference?
Radius of circle times 2, multiply that by pi (3.14 for easyish reckoning), and that's the circumference of a circle. The circumference of an object is the distance around the outside or perimeter. Different formulae are used to calculate this depending on the shape.
What is the circumference of a circle if the diameter is 2.6Cm?
The circumference formula is C=3.14(or pi) times diameter so from there, you plug in. C= 3.14( use pi on your calculator to make it more accurate) times 2.6 so the approximate circumference of that circle is 8.164 if you used 3.14 instead of pi. if you used pi, your answer would be about 8.168
What is a circumference used?
The circumference is the measurement around a circle
What do people use pi for?
Since pi is the ratio of the circumference of any circle to its diameter, it comes up any time a radius or diameter is used to calculate most other characteristics of a circle or a sphere, such as circumference, area, surface area or volume, or whenever any of those characteristics are used to calculate a radius or diameter.
Why is pi a useful number?
It is used to calculate the circumference and the area of a circle, the surface area and volume of a sphere, to calculate areas and volumes of some other geometrical figures, and in several applications in advanced math that are seemingly unrelated to the circle.
How is pi used to calculate the circumference?
pi times diameter = circumference
Why is pi used in circle?
Because the ratio of the circumference of any circle to its diameter is pi.
