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.
Circumference of circle: 2*pi*36 = 226.195 cm rounded to 3 decimal places
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.
you multiply the diameter by pi which is approximately 3.14
The circumference will be 7*pi feet
area = pi * radius* 2
pi x the square of the radius
By definition Pi is the relation between the radius and circumference of a circle.
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)
circumference = 12*pi = 37.699 yards to 3 decimal places
A radius is not part of pi.
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
