How do you find the circumference of a circle without knowing the area?
To find the circumference of a circle, you need only know the radius or diameter of the circle. The circumference of a circle is calculated as 2 x Pi x radius OR Pi x diameter. Pi is approximately 3.1415926.
How do you find the perimeter if you already know the circumference of a circle?
The circumference of a circle is the length of the circle's perimeter.
How do you convert area of circle if you know the circumference?
It depends on what you want to convert the area of the circle into.
How do you find the circumference of a circle of you know the area?
Divide the area by pi, which gives you the square of the radius. Take the square root and multiply by 2 pi and you have the circumference.
What formula do you use if you know the diameter of a circle and want to find the circumference?
circumference of a circle = pi * diameter.
How do you find the diameter of a circle in the terms of pi?
To find the diameter of a circle, you will either need to know the area or its circumference. If you know the area: diameter = 2 x squareroot(area / Pi) If you know the circumference diameter = circumference / Pi
How do you find the circumference of a circle when you know the area?
To find the circumference of a circle when you know the area, you first need to find the radius of the circle using the formula for the area (area = πr^2). Once you have the radius, you can calculate the circumference using the formula for the circumference (circumference = 2πr).
How do you fund the circumference of circle when you know the area?
You dived the area by the circumference of the circle.
When you know the circumference of a circle how do you find the diameter?
If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
How do you find the area of a circle if the circumference is 10?
We know that the area of a circle is pi * r2. We also know that the circumference of a circle is pi * d. Therefore, when you know the circumference of a circle and want to know the area, divide the circumference by pi to give you the diameter of the circle, divide the diameter by 2 to give you the radius, square the radius and then multiply by pi to get the area. So, 10/pi = 3.183. 3.183/2 = 1.5915. 1.59152 = 2.533 2.533 * pi = 7.958 to 3 decimal places. The area of your circle is therefore 7.958cm2.

The circumference of a circle is the length of the circle's perimeter.
How do you find the area of a circle when you already know the circumference?
radius = circumference/(2*pi)area = pi*radius2So Area in terms of Circumference is A = pi [C/2pi]2or (circumference)2/4 pi
How do you find the diameter of a circle if you know the circumference?
Divide the known circumference by pi to find the diameter of the circle.
How do you convert area of circle if you know the circumference?
It depends on what you want to convert the area of the circle into.
How do you find the circumference of a circle of you know the area?
Divide the area by pi, which gives you the square of the radius. Take the square root and multiply by 2 pi and you have the circumference.
How do you calculate the area of a circle if you know the circumference?
By dividing its circumference by 2*pi will give the radius of the circle and its area = pi*radius2
