Circumference is the enclosing boundary of a curved geometric figure, especially a circle.
Radius is a straight line from the center to the circumference of a circle or sphere.
Pi is the numerical value of the ratio of the circumference of a circle to its diameter and does not have a circumference or radius of its own.

What is the cercumference of a circle with a radius of 36cm?
Circumference of circle: 2*pi*36 = 226.195 cm rounded to 3 decimal places
What is the square foot area of a circle 128 foot cercumference?
A circle of radius r has a circumference of 2*Pi*r and an area of Pi*r*r, where Pi is the constant which is approximately 3.14159. Use the first equation to calculate the radius and then the second to calculate the area.
What is the radius of a circle if cercumference equals 17?
2.7
How do you find the cercumference of a circle?
you multiply the diameter by pi which is approximately 3.14
If diameter is 7 feet what is cercumference?
The circumference will be 7*pi feet
What is he definition of area?
area = pi * radius* 2
What is the definition of the area of a circle?
pi x the square of the radius
Why is pi used in every circle formula?
By definition Pi is the relation between the radius and circumference of a circle.
How do you find the area of a circle if you know the circumference?
Circumference = pi x diameter = pi x 2 x Radius (By definition - Step 1) So Radius = (Circumference)/(pi x 2), (find Radius - Step 2) Area = pi x Radius x Radius, (substitute value or radius obtained in step 2)
What is the cercumference of the circle if d12 yd?
circumference = 12*pi = 37.699 yards to 3 decimal places
If the circumference of a circle doubles the radius?
IMPOSSIBLE circumference = 2*pi*radius if circumference = 2*radius: 2*radius=2*pi*radius 2*radius/(2*radius)=2*pi*radius/(2*radius) 1=pi pi= 1 therefore it is impossible to have a circumference that is twice that of the radius
What is the radius 2.6 in in pi?
A radius is not part of pi.
