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 if the radius is 80m?
the way you find the circumference is 2xpixr or pixdiameter. so it would be 2x80xpi
What is all the way round the outside of a circle called?
Circumference and the formula for circumference is C=πd or C=2rd
How do you find circumference of a circle the easy way?
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 :)
Can a chord be in the middle of a circle?
Not sure what you mean by "in the middle of a circle". A chord must have each of its ends on the circumference of the circle. If a chord is such that is passes through the centre point of the circle, it is (the longest chord possible and is) called a diameter. Or to put it another way, a diameter of a circle is a chord which passes through the centre point of the circle.
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 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
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)
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 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.
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

How do you find circumference of a circle the easy way?

What is another way to find the area of a circle given the circumference?
Divide by pi to get the diameter. Divide the diamater by 2 to get the radius. Pi times radius squared.
Can a chord be in the middle of a circle?

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
