You do not solve the diameter. You can either measure it or you can CALCULATE it. Calculation depends on what information you do have. There are different formulae which depend on whether you know the radius, the circumference, the area, the volume (if a sphere), the angle between tangents from a point at a known distance from the centre etc.

What is the diameter of a circle if the circumference of ten feet?

Circumference=Diameter*pi so plug in 10 = Diameter * pi and solve. I hope you can do this by your self from here


How do solve circumference?

The circumference of a circle is 2*pi*radius or diameter*pi


What is the formula for finding diameter when given the area?

Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.


How do you find the diameter a the cylindeer base if you know the height and volume?

Volume = Pir2 X height Diameter = 2r Pi = 3.1416 Solve for diameter Volume/height = 3.1416(diameter/2)2 (square root of (Volume/height/3.1416)) X 2 = diameter of the cylinder base


How do you get the diameter if you only know the circumference?

Circumference is pi * d. Solve for d. d = Circumference / pi


If a square is inscribed in a circle the diameter of the circle is congruent to?

The diameter of the circle is congruent to the length of the diagonal of the inside square. If you know the length of one side of the square, you can use pythagorean's theorem to solve for its diagonal (hypotenuse) and thusly the square's diameter.


What is the diameter of a circle with a 128ft circumference?

The formula for the circumference of a circle is 2*pi*radius or pi*diameter. In this case, it's 128=pi*d. Solve for d, and you get 40.74 feet.


The area of circle is 1024 pie square meter what is the diameter?

Solve the equation for the area of the circle (area = pi x radius2) for radius. Multiply the radius by 2 to obtain the diameter.


How do you you calculation the diameter with circumferance?

The formula for circumference is Pi x D= Circumference. If you know the circumference you solve for the diameter as you would any other variable. Let's say the circumference is 10, the equation would then be: Pi (3.14) x D = 10. Solve for D. D= 10/3.14


What is the diameter of a circle that is 169 pi square yards?

Use the formula for the circle: area = pi x radius squared. Replace the area, and solve for the radius. Multiply the radius by 2 to get the diameter.
