A circle has an infinite number if diameters, but they are all the same length. The length of the diameter of a circle is the length of the longest straight line that can be drawn completely inside the circle. If the center of the circle is marked, then it's easy to draw a line that is a diameter ... it's any line that passes through the center of the circle.

What do you multiply to get the circumference?
The circumference of a circle is worked out by multiplying the diameter of the circle by pi.
Why is pi not a rational number?
That's just the way it worked out. Pi is the ratio of the circumference of a circle to its diameter, and it just worked out that this ratio is an irrational number.
What is the area of a cylinder with a diameter of 4 and radius of 7?
The given dimensions are impossible and so finding its area can't be worked out.
What is the diameter of a Papa John's large pizza?
18 inch
What is the diameter of a ball whose volume is 28 cubic inches?
First we have to find the radius because the diameter is twice the radius: 4/3*pi*radius3 = 28 radius = 1.883749459 (worked out by making the radius the subject of the formula) diameter = 3.767498918 or 3.77 inches to 2 d.p.
How was the value of pi ditermined?
The value of pi is determined by dividing a circle's circumference by its diameter and an exact value has never been worked out because pi is an irrational number.
Can a circle have perimeter?
Circles do have a perimeter, which is known as the circumference. The circumference is worked out by multiplying:2, Pi, Radius (r)Pi, Diameter (d)Hope that's helpful for you!
How do you find circumference of a circle the easy way?
You need to know the radius first. Next you simply double the radius to get the diameter and then multiply that by pie and you have now worked out the circumference of your circle :)

What is the diameter of a circle that is equal to pi?
If you mean the diameter of a circle with area pi, then the diameter is 2. If you mean the diameter of a circle with circumference pi, then the diameter is 2. If you mean the diameter of a circle with diameter pi, then the diameter is pi. If you mean the diameter of a circle with radius pi, then the diameter is 2pi.
