What is diameter of a 130mm circumferance?

To find the diameter of a circle given its circumference, you can use the formula: diameter = circumference / π. In this case, the circumference is 130mm. So, the diameter would be 130mm / π ≈ 41.34mm.

What is the diameter if the circumference is 84?

To find the diameter of a circle when given the circumference, you can use the formula: circumference = π * diameter. Given a circumference of 84 units, you can plug this value into the formula and solve for the diameter. Dividing 84 by π gives you approximately 26.67 units as the diameter of the circle.

What is the diameter of a circle whose circumference is 47.1cm?

Well, isn't that a happy little question! To find the diameter of a circle when you know the circumference, you can use the formula: diameter = circumference / π. So, for a circumference of 47.1cm, the diameter would be 47.1 / π ≈ 15cm. Just imagine that circle coming to life on your canvas, bringing joy and balance to your painting.

How do you find a radius given the diameter?

The radius is one half of the diameter. If the diameter is 20, the diameter is 10.

How do you find the radius with the given diameter?

radius is half diameter...so divide diameter by 2!!!
