When do you need to find the circumference of a circle?
circumference of a circle = 2piradiuis or diameter*pi
Why would you need to find the circumference of a circle?
As for example when constructing a round-about on a road you'll need to know its perimeter which is the circumference of a circle.
What is a situation where you would need to know the circumference of a circle?
The circumference of a circle would be needed as for example when constructing a circular swimming pool.
Why do you need Pi?
So that you can find the circumference of a circle.
Is an arc a fraction of a circumference?
It is part of a curve. If that curve happens to be a circle, then it is a fraction of a circumference but it need not be.
When do you need to find the circumference of a circle?
circumference of a circle = 2piradiuis or diameter*pi
How do you figure out diameter?
Assuming you are talking about a circle:* If you know the radius of the circle, multiply that by 2. * If you know the circumference of the circle, divide that by pi. * If you know nothing, you need to measure either the radius, the diameter, or the circumference.
Why would you need to find the circumference of a circle?
As for example when constructing a round-about on a road you'll need to know its perimeter which is the circumference of a circle.
How do you covert area into circumference?
Well, you can't really "convert" it, but I assumeyou want to calculate the circumference from the area. First, you need to know what figure you are talking about. For the specific case of a circle, I suggest you use the formula for the area of a circle, replace the known area, and solve for the radius. Once you have that, it is easy to calculate the circumference.
How do you find the circumference of a circle when you know the area?
OK, SO to find the area of a circle, you find the radius (half of the diameter), and fit it into the equation πr2=A where r equals radius and A = area. The perimeter of a circle is π multiplied by the diameter. π is ≈ 3.1415296.
What is a situation where you would need to know the circumference of a circle?
The circumference of a circle would be needed as for example when constructing a circular swimming pool.
Why do you need Pi?
So that you can find the circumference of a circle.
What are other equations for circumference?
One definition of circumference is the boundary line of a circle and is related to π and the circle's diameter by the equation π=C/D where C is the circumference and D the diameter of the circle. A second, more general definition is the boundary line of any closed curvilinear figure. Synonyms are periphery and perimeter. Two equations for the circumference of a circle are C=πD=2πr where r is the radius. To get other equations, you need to specify the closed curve for which you want the perimeter.
How do you solve the circumference of a circle?
to find the circumference of a circle, which is the distance in the outside of the circle you need to use the following formula: C=dx 3.14 or circumference equals diameter times pi. The diamater is the length of the circle from end to end. Not very difficult.
What is the diameter of a circle with 52cm as circumference?
16.55cm - If you want to work it out, you will need to divide the circumference by pi.
Is an arc a fraction of a circumference?
It is part of a curve. If that curve happens to be a circle, then it is a fraction of a circumference but it need not be.
How do you find circumference of concentric circles?
You need to know diameter of each circle, which are different for each circle; each circle circumference is pi x diameter where pi = 3.14159
