What is the formula for the diameter of a circle?
The diameter of a circle is twice its radius, or 2r.
What is the formula for the circumference of a circle if the diameter is 8.70 m?
The formula for the circumference of a circle is the same, whatever its diameter. Circumference = pi*diameter.
How to calculate the diameter of a circle when the circumference of the circle is 7?
pi*diameter = circumference Rearrange the formula so as the diameter is the subject of the formula: diameter = circumference/pi diameter = 7/pi = 2.228169203
How do you work out the area of a circle in a square?
The formula for the area of a circle is pi x radius2. The radius is half the diameter, and the diameter of an inscribed circle is the same as the length of a side of the square.The formula for the area of a circle is pi x radius2.
