What is diameter of circle if radius is 1.5?
A diameter of a circle is twice the length of a radius. Think of a diameter as two radii, both originating at the center of the circle and extending out at 180 degrees to each other to reach the edge of the circle. In this example, if the radius is 1.5, the diameter would be 3.
How do you determine the length of the radius and diameter of a circle?
The answer depends on what information you are given. If you know the circumference, then divide by Pi and that is the diameter. Half of the diameter is the radius. If you don't know anything about the circle, you would need to measure and find the diameter.
If the diameter of a circle is 4 centimeters what is the length of the radius?
Length of a radius is always half the diameter of a circle. This means that the circle has a radius of 2cm.
Is the diameter of a circle twice the size of the radius?
Yes, the diameter of a circle is twice the length of the radius.
What is the relationship between the diameter of a circle and its radius and vice versa?
The diameter of a circle if twice the length of the radius.
What does the diameter of a circle measure?
The length across the circle. 2 x the radius.
What must be done first when finding area of a circle marked with a diameter?
Measure the length of the diameter in suitable units!
How do you find the diameter of a circle with the width and length?
The width, or the length of a circle are its diameter.
What is the length of the diameter of 9 in?
the diameter is the length. the diameter means the length of across the circle. it means the longest length across the circle. the radius is halfthe diameter
Diameter vs radius?
diameter is length all the way across a circle radius is half of the diameter which is a dot in the center of the circle and it goes to all sides of the circle and it equals the same # throughout the 360 degrees
How do you figure out the circumference of something without knowing the diameter?
If you know the radius, double that to get diameter. If you have neither radius or diameter, then measure around the outside.
What kind of unit does a circle have?
A circle can have a unit of length which could be either a measure of its diameter or radius, or of its circumference. Or the circle could have the unit of area.
How do you find the diameter?
The diameter of a circle is the length of a straight line drawn through the center of the circle to its edges.Or, measure the circumference of the circle and divide by pi (3.14159).Or you can multiply the radius times twoTo get diameter you have to find the radius and then double it to get the diameter
What is the relationship between the length of the diameter of a circle and length of the radius of that circle?
The diameter of any circle is twice its radius
What is the length of a radius and the length of a diameter?
The length of a radius of a circle is half of the diameter of the same circle. So, diameter is always twice the radius.
How does the length of the diameter of a circle compare to the length of the radius of that circle?
diameter = 2 X radius
What is diameter of circle if radius is 1.5?
A diameter of a circle is twice the length of a radius. Think of a diameter as two radii, both originating at the center of the circle and extending out at 180 degrees to each other to reach the edge of the circle. In this example, if the radius is 1.5, the diameter would be 3.
