Why is Pi used to calculate circumference and area of circles?
Because of the radius of the circle
What is the circumference of a circle if the radius is 27 inches?
The circumference of a circle if the radius is 27 inches is: about 169.6 inches. (you can do this type of calculation for other circles using this formula: r x 2 x Pi = circumference).
What is the relationship between the radius of a circle and the circumference?
any circles circumference divided by its diameter will equal pi, or 3.14159 approximately
What is thr relationship between pi and circles?
Circumference of a circle is 2 x Pi x the radius
What does pi mean?
Pi (3.14) times the radius of a circle squared, equals the circumference of a circle.
How do you find the circumference of circles?
The circumference of a circle = pi*diametre = 2pi*radius
How big of circles can you calculate their circumference?
Any circle's circumference can be calculated with the formula 2(pi)*radius
Why is Pi used to calculate circumference and area of circles?
Because of the radius of the circle
How is pi used to find the circumference of circles?
Circumference of any circle = 2*pi*radius or pi*diameter
What is the circumference of a circle if the radius is 27 inches?
The circumference of a circle if the radius is 27 inches is: about 169.6 inches. (you can do this type of calculation for other circles using this formula: r x 2 x Pi = circumference).
What is the relationship between the radius of a circle and the circumference?
any circles circumference divided by its diameter will equal pi, or 3.14159 approximately
How do you make a project?
area of the circle is half the product of its circumference and radius by coiling method (for 10 circles of different radius).
How do you find a circles radius when they only tell you the circumference of the circle?
Divide by pi and then divide by 2
What is circumference of a circle in terms of pi?
The circumference of a circle is 2 pi r, where r is the radius, or it is pi d, where d is the diameter.there is no circuference of pi. Circumference refers to the outer edges of circles
What is thr relationship between pi and circles?
Circumference of a circle is 2 x Pi x the radius
What does pi mean?
Pi (3.14) times the radius of a circle squared, equals the circumference of a circle.
Who discovered circumference of circle?
The ancient Greek mathematician Pythagoras is usually creditted for the discovery of the ratio of circumference to radius of circles. That is, Circumference = 2 * Pi * Radius. The number Pi represents (3.1415....) is named after him.
