What is the diameter of a circle with 12cm?

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

Can you find the diameter of a circle from the circumference?

Circle/Diameter

What is the diameter of a circle with circumference 22pi cm?

Therefore , 2r = 7 cm. Hence the diameter is 7 cm.

What is the diameter of a 6 cm circumference circle?

If r = 6 cm, the the circumference is c = 2π(6) = 12π cm, if writing in terms of π. If you prefer a numerical value, the answer rounded to the nearest tenth is 37.7 cm. Suppose you only know the diameter?

What is the diameter of a 11cm circle?

Answer the radius of the circle measuring 11 cm diameter is 5.5 cm.

What size is 12 cm in inches?

Centimeters to Inches table

Centimeters Inches
10 cm 3.94 in
11 cm 4.33 in
12 cm 4.72 in
13 cm 5.12 in

What’s the area of a 4cm circle?

The area of a circle is equal to Pi π times the radius r squared. Substitute in the value of the radius r=4 into the formula for the area of a circle. Pi π is approximately equal to 3.14 . Raise 4 to the power of 2 .

What is diameter if circumference is known?

If you want to find the diameter from the circumference of a circle, follow these steps: Divide the circumference by π, or 3.14 for an estimation. And that’s it; you have the circle’s diameter.

How do you find circumference?

To find the circumference of a circle, multiply the circle’s diameter by pi (3.14).

What is the diameter of a circle if?

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter.

How do you find circumference with area?

The formula C = 2√πA is designed to find a circle’s circumference using the area (A). Alternatively, you can solve the equation A = πR2 in reverse to find R, then plug R into the circumference equation. Both equations provide the same result.

How to calculate the diameter of a circle?

Circumference to Diameter Calculator. This circumference to diameter calculator is used to find the diameter of a circle given its circumference. Just enter the value of the circumference. Then tap or click the Calculate button. Get the result. You can also select units of measure for both input data and results.

What are the three dimensions of a circle?

There are three dimensions most often used to describe a circle: 1 The diameter – defined above 2 The radius – the distance from the circle’s center or origin to the edge, one half the diameter 3 The circumference – the length of the outside boundaries of the circle More

How is the perimeter of a circle defined?

Circumference or perimeter of a circle is defined as the distance around it. The diameter of a circle is the straight line passing through the center of the circle. It is also called as the longest chord of the circle. This online diameter to circumference converter helps you to find the perimeter value from the given diameter at desired units.

What is the circumference of a circle called?

The circumference of a circle is the distance around the outside of the circle. It is like the perimeter of other shapes like squares. You can think of it as the line that defines the shape. For shapes made of straight edges this line is called the perimeter but for circles this defining line is called the circumference.
