How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
What is the required piece of information tho find the area of a circle?
The only piece of information required to find the area of a circle is the radius of the circle. Once you know the radius of the circle, the area is simply the radius squared multiplied by pi (approximately 3.14).
How do you determine the radius if you only have the diameter?
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
What is the area of a circle with a radius of 3 in by 4 in?
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.
What is the radius of a circle with the diameter of 56 centimeters?
The radius of a circle is half of the diameter, so if the diameter is 56cm the radius can only be 28cm.
How do you find the radius of a circle if you only know the area?
Radius = +sqrt(Area/pi)
How do you find the area of a circle if you only know its circumference?
Divide its circumference by 2*pi which will give the radius of the circle. Area of the circle then is pi*radius squared
How do you find the equator of a circle if you only know the radius?
Multiply the radius by 2, and then by pi. pi=3.141592654...
What is the formula for finding the circumference of a circle when you only know the radius?
Circumference = 2 x pi x radius

How do you determine the radius if you only have the diameter?
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
What is the radius of a circle if you only know the perimeter?
Divide the perimiter, or circumference, by pi (3.1415), which is the diamter, then divide that by 2 to get the radius
What is the area of a circle with a radius of 3 in by 4 in?
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.
What is the radius of a circle if you only know the circumference?
Easy. If you only have the circumference, divide it by Pi (about 3.1416). This gives you the diameter. Next, divide the diameter by two to get the radius.
How do you find the radius when you only have area of a circle?
Use the formula area = pi x radius2. If you replace everything you know, you can solve for the radius.
Can the radius of a circle be found if you only have a piece of the circle?
If you have the area of the piece and you know how much the piece takes up. For example if you have a piece of a circle and you know it is 1/4 if the circle then you take the area and multiply by 4.
What is the radius of a circle with the diameter of 56 centimeters?
The radius of a circle is half of the diameter, so if the diameter is 56cm the radius can only be 28cm.
