A circle has the same diameter all the way around.
You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.You measure it. If you know the radius (of a circle), you multiply it by 2 to get the diameter. If you know the circumference of a circle, you divide by pi to get the diameter.
That depends on what you know. If you know the radius of the circle, double it to get the diameter. If you know the circumference of the circle, divide it by π to get the diameter. If you know the area of the circle, find its square root and divide the result by π to get the radius then multiply by 2 to get the diameter.
Did you know that the sun is circle shaped?
The circumference of a circle is the length of the circle's perimeter.
If you know the circle's Radius, the area is [ pi times r2 ]. If you know the circle's Diameter, the area is [ 1/4 pi D2 ].
2.4 halfs of a circle is 31.5 and yes, it is called a seme circle. is that the same as semi circle as I know it?
measure it
The largest chord of a circle is its diameter
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.
You dived the area by the circumference of the circle.
Area of a circle = pi*radius2
When you know the circle's radius (r): pi X r2 When you know the circle's diameter (d): pi X (d/2)2
