diameter = 13.99645085 or about 14 inches
Measure the length of the diameter in suitable units!
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
You must find the circumference. First measure a line through the cirle. Then that is the diameter then multiply the diameter by 3.14 then you have the area! Hope that helped!
The diameter of a circle with an area of 37.68 is 6.92
circumference of a circle = 2*pi*radius or pi*diameter area of a circle = pi*radius squared
A circle can have a unit of length which could be either a measure of its diameter or radius, or of its circumference. Or the circle could have the unit of area.
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared Radius of a circle = diameter/2 Degrees around a circle = 360 degrees
A circle is fully defined by just one measure - its radius or diameter or circumference of area. I am sure there cannot be a circle with two measures as in the question!
The area of a circle with the diameter of 3m is 7.069 m2
The area of a circle with diameter of 4.9 is 75.43 units2
To find area of a circle using diameter, you use this formuler. Area=pi(diameter/2)(diameter/2)
The area of a circle with a diameter of 9.4 m is: 69.4 m2
