## How do you figure out a diameter?

How To Calculate Diameter?

- Diameter = Circumference ÷ π (when the circumference is given)
- Diameter = 2 × Radius (when the radius is given)
- Diameter = 2√[Area/π] (when the area is given)

## What is the diameter of 35cm?

The radius of a circle is half its diameter. The radius of a circle with a diameter of 35cm is 17.5cm.

## How do you find the diameter from volume?

The diameter of a sphere formula with volume is, d = (6V/π)^(1/3), where d is the diameter of the sphere and V is its volume. Alternatively, we can substitute the value of V, in the volume formula, V = (4/3) π r3, solve it for r, and make it double to find the diameter.

## What is a diameter in math?

Definition of diameter 1 mathematics : a chord (see chord entry 3 sense 2) passing through the center of a figure or body. 2 mathematics : the length of a straight line through the center of an object or space the diameter of a circle dug a hole nearly four feet in diameter.

## What is the diameter of 12 cm radius?

So, if d=12 cm, r=12(12)=122=6 cm.

## What is a circle diameter?

The diameter is the length of the line through the center that touches two points on the edge of the circle.

## What is the diameter of a 4 inch circumference?

Circumference & Areas

Size in Inches | Circumference Inches | Area in Square Inches |
---|---|---|

3 3/4 | 11.780 | 14.060 |

4 | 12.570 | 16.000 |

4 1/4 | 13.350 | 18.060 |

4 1/2 | 14.140 | 20.250 |

## How do you find the diameter of a circle without the radius?

Divide the circumference (perimeter) by pi. That gives you the diameter.

## Is diameter a volume?

Volume is the three-dimensional amount of space that an object occupies. Volume has dimensions of length cubed; for example, cubic feet of material, or cubic centimeters (cc’s). Notice: On all of the shapes that have curved (circular) surfaces, we are using the diameter of the circle in the derivation of the volume.

## What is an example of a diameter?

Diameter is defined as the length of a straight line through the center of a circle. An example of a diameter is the length of a line sliced down the center of a pie. A straight line segment that passes through the center of a circle or sphere from one side to the other.
