Is diameter half the circumference?
The distance around a rectangle or a square is as you might remember called the perimeter. The distance around a circle on the other hand is called the circumference (c). Half of the diameter, or the distance from the midpoint to the circle border, is called the radius of the circle (r).
What is the length of a diameter?
The diameter is the length of the line through the center that touches two points on the edge of the circle.
How do you convert length to diameter?
Multiply the radius by 2 to find the diameter. For example, if you have a radius of 47 inches, multiply 47 by 2 to get a diameter of 94 inches. Divide the radius by 0.5 to calculate the diameter. In this example, check your answer by dividing 47 by 0.5 to verify your answer of 94 inches.
How do you work out the length of a diameter?
If the radius of a circle is , then the diameter would be \displaystyle 2r = 2(6) = 12. Therefore, the length of would be \displaystyle 2d = 2(12) = 24.
What is the diameter of a 10 inch circle?
How do I find diameter if I know circumference? Solve the equation for the diameter of the circle, d= C/π. In this example, “d = 12 / 3.14.” or “The diameter is equal to twelve divided by 3.14.” Divide the circumference by pi to get the answer….What is the diameter of a 10 inch circle?

How big is 18 inches round?
Explanation: The formula for circumference is π d, meaning pi (~3.14) times the diameter of the circle. Plugging in 18 for d, you get π (18), which equals 56.548667… You specified it needed to be rounded to the nearest tenth of an inch, so you’d round that to 56.5 inches.
