Give an example of direct proportion?
The Circumference of a circle is directly proportional to the diameter. The constant of proportion is 'pi = 3.141592....'. Another one is force is directly proportional to mass. The constyant of proportion is acceleration.
If a circle has a diameter of 6 what is the circumference?
Circumference of circle = Pi X D (3.1416 X Diameter of 6) = 18.8496 18and 1/2 inches 3.14 is constant, thus, 6x3.14=18.84 18.84 is the answer.
If the radius of a circle is six inches then the diameter is how many feet?
The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.The diameter of a circle is twice the radius.
Is the largest chord on a circle the diameter of the circle?
Yes, the largest chord of a circle is its diameter.
Half the diameter of a circle?
Half the diameter of a circle is called its radius.
What is the mathematical relationship between the circumference of a circle and its diameter?
The circumference of a circle when divided by its diameter is the value of pi which is an irrational number.
What shape is constant in diameter other than a circle?
None. The only shape with a diameter is the circle.

Is a circle a constant width curve?
Yes its diameter is its width which is constant where ever it's measured inside the circle
What is the ratio of the circumference and diameter of a circle?
The circumference of a circle divided by its diameter is a constant referred to as Pi, and is roughly equal to 3.14156.
How do you find the circumference of a circle using the length of the diameter?
Multiply the diameter by the constant pi.
In a circle the circumference and diameter vary directly Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second ci?
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
How is pi related to the diameter of a circle?
Pi is related to the diameter of a circle through the circumference. C=(pi)*d C = circumference (perimeter of the circle) pi = constant d = diameter
The distance directly through the middle of the circle?
diameter
How many lines of symmetry does a circle have What are they?
A circle has an unlimited number of lines of symmetry. These lines are called the diameter. Why does a circle have an unlimited number of lines of symmetry? It's because a circle has a constant diameter regardless of where the diameter is measured from.
Why the value of pi is constant?
The value of pi is constant. It is calculated by dividing the circumference of a circle by its diameter. As the circle's circumference grows, the diameter grows at the same rate, proportionally. This means that the circumference divided by the diameter (if measured precisely) will always yield pi. If it does not, it is not a perfect circle. The ratio between the circumference and the diameter of a circle will always stay the same, no matter how you change the size of the circle.
What are two quantities whose ratio is constant?
The diameter and circumference of a circle.
