You need to know the radius first. Next you simply double the radius to get the diameter and then multiply that by pie and you have now worked out the circumference of your circle :)

What is the circumference of the circle if the radius is 80m?
the way you find the circumference is 2xpixr or pixdiameter. so it would be 2x80xpi
What is another way to look at the circumference of a circle?
The circumference of a circle is its perimeter
What is all the way round the outside of a circle called?
Circumference and the formula for circumference is C=πd or C=2rd
Circumference of circle with 18 meter diameter?
if a circle has an 18 meter diameter, then it has a 9 meter radius the circumference of a circle is 2(pi)r so the c. would be 2(pi)(9) which is 18pi. (another way to think of circumference is the diameter times pi)
What is the circumference of the circle with a diameter of 11?
since the circumference of a circle is pi*diameter, the diameter would be equal to 11pi. You CAN multiply 11 by pi, but it isn't really helpful in any way IN THIS CASE
What is an easy way to remember how to find the circumference of a circle?
Cherry Pie is delicious.C= πd
What is a way to remember how to spell the word circumference?
the easy way to remember circumference is to remember circle the CIRCumference measures the distance around a CIRCle
What is the circumference of the circle if the radius is 80m?
the way you find the circumference is 2xpixr or pixdiameter. so it would be 2x80xpi
What is another way to look at the circumference of a circle?
The circumference of a circle is its perimeter
Do you have to find the radius for diameter?
Not necessarily. The diameter is only twice the radius, so that's an easy way to find the diameter. However, if you have the circumference, you can divide by pi to get the diameter, or just measure across the circle.
Is circumference larger than radius?
Yes it is. Circumference is the whole area of the circle. Radius is from the middle to the side of the circle. Yes it is. The radius it half way across the circle from the center, while the circumference is all the way around the circle. The diameter is all the way across the circle, while being twice the radius. The circumference is about 3.14 times the diameter (or Pi if you prefer).
What is the relationship between the circumference of a circle and its diameter?
The circumference of a circle is equal to pi times its diameter. Another way to say this is that for any circle, circumference divided by diameter will always have pi as the answer, regardless of the size of the circle.
What is the relationship between the Radius to the circumference?
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.
How is pi useful?
the way to use pi is to find the circuference of a circle
Where and how pi it is used today?
Pi is used in many ways today. The simplest way it to find the circumference (the perimeter) of a circle or the area (amount of space inside) of a circle.
What is all the way round the outside of a circle called?
Circumference and the formula for circumference is C=πd or C=2rd
Circumference of circle with 18 meter diameter?
if a circle has an 18 meter diameter, then it has a 9 meter radius the circumference of a circle is 2(pi)r so the c. would be 2(pi)(9) which is 18pi. (another way to think of circumference is the diameter times pi)
