The diameter is a straight line from one side of the circle to the other which passes through the centre of the circle. The radius is a straight line from the centre to the boundary of the circle. To label them, you could either write the words alongside the lines or, if the circle is too small, draw arrows from the two lines to outside the circle and write the words at the end of the arrow.
What else can I help you with?
If i draw a circle that has a diameter of 2 centimeters what is the radius of the circle?
1 centimeter
Show me a 7mm circle?
It is hard to draw one here and do you mean radius 7 mm or diameter 7mm
Is it possible to draw a circle of negative radius?
Radii are always positive. No, it is not possible to draw a circle with negative radius.
How can a compass help in math?
A compass can be used to calculate distance by angle and to help draw circles as well as finding the radius, diameter, and circumference of the circle.
How do you find a chord of a circle with diameter 26?
There are an infinite number of possible chords in anycircle, regardless of its diameter. A chord is a line segment with its endpoints on the curve (circumference) of the circle. You can draw those all day and never draw the same one twice.
If i draw a circle that has a diameter of 2 centimeters what is the radius of the circle?
1 centimeter
What is a radiu s of a circle?
If you draw a line from the center of a circle to the edge of a circle, you have drawn the radius of the circle. If you draw a line from the edge of a circle through the center of the circle and on to the edge on the opposite side, you have drawn the diameter of a circle. The radius of a circle is one half the diameter of a circle.
How do you find tha radius?
The radius is half the diameter. Draw a line that passes through the centre of the circle and measure it. This is the diameter. Halve it and you will have the radius.
Draw a circle of 6 cm and find the radius?
If the diameter is what you are talking about that is 6 cm, you must divide that number by two to find the radius because the radius is half a diameter. The radius of a circle with a diameter of 6 cm. would be 3 cm.
How do you draw a diameter in a circle?
The diameter of the circle is the length running through the center. From one side to the other. Note: Two times the radius, equals the diameter.
How can you use a compass to draw a circle if you know its raduis or diameter?
If you know the radius place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle. If you know the diameter divide by two to get the radius and place the compass point on a ruler and the pencil end the radius distance away from it. Then put the point on the paper and spin to draw the circle.
How do you make the r in a circle?
The 'r' means the radius, exactly half of the diameter. Find the centrepoint of the circle, then draw a line from the centre to the outside. This line is your radius.
Is it possible to draw a circle whose ratio of circumference to diameter is not pi?
No, the circumference divided by the radius will always be pi for a circle.
How do you find the diameter using radius?
Radius is just a fancy name for half a circle across; a diameter is another fancy name for whole across. So it would be like draw a horizontal line across a circle so if u have the radius...multiply it by two and you have your diameter
What is the definition of radius and diameter?
If you draw a line from one side of a circle to the other, and that line hits the center, and goes all the way across, it is the diameter. half of that line going from the center to the edge of the circle is the radius.
What is the radius of a circle if the diameter is 8 inches?
The radius is the distance from the center of the circle to its edge. The diameter is a straight line passing from one point on the edge to another which passes through the center. Draw these and you will see that the diameter is really just two aligned radii, so the radius is always exactly half of the diameter.
Show me a 7mm circle?
It is hard to draw one here and do you mean radius 7 mm or diameter 7mm
