Ah, what a delightful question! The radius of a circle fits into the circumference of the circle exactly 2 times. Just imagine the radius wrapping around the circle, giving it a warm hug, and then doing it one more time for good measure. It's a beautiful relationship between the radius and the circumference, creating harmony and balance in the circle's lovely shape.
The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.
The equation for the circumference of a circle is pi times radius squared.
circumference= pi(3.14) by the diameter. if your given the radius, double the radius and times by pi.
The formula for the area of a circle is pi times the radius squared. The formula for the circumference of a circle is two times pi times the radius.
The ratio of a circle's circumference to its area is called the reciprocal of half the radius. The ratio of the circumference to its radius is called two times pi.
The ratio of the circumference to the radius of the circle is 2 times pi
The circumference of a circle is 2*pi*radius or pi*diameter
The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.
area: pi times radius squared circumference: pi times radius
The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.
the circumference of any circle is 2PIr or two times PI(3.14) times the radius (in this case, 16). do the math.
The circumference of a circle is two times pi times the radius.
Circumference of the circle is: 2 times pi
The equation for the circumference of a circle is pi times radius squared.
The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.
The circumference of any circle is (2 pi) times (radius) .Now you can do any circle on your own.
The circumference of a circle is equal to the radius times 2*pi. 2*pi*R where R is the radius.
