## What is the diameter of 6cm radius circle?

Answer: The diameter of the circle will be 12 cm.

### What is the length of the diameter of a circle of radius a?

Diameter of a Circle Using Radius Radius is the length of the line segment from the center of the circle to an endpoint on the circle and diameter is twice the length of the radius of the circle. Using this definition, the formula for the diameter is: D = Radius × 2.

#### How do you find the length of the diameter of a circle?

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.

**What is the circumference of a 6 cm circle?**

12π cm

Finding the Circumference: 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.

**What is the area of a 6 circle?**

28.27 sq. units

Answer: The area of a circle with a diameter of 6 units is 28.27 sq. units or 9π square units.

## How to calculate the diameter of a circle?

The formula used to calculate circle diameter is: ø = 2 · r. Symbols. ø = Circle diameter; r = Circle radius; Radius of Circle. Enter the radius of a circle. The radius is the distance between the centre and any point on the outer edge of a circle. Diameter of Circle. This is the diameter of a circle that corresponds to the specified radius.

### 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

#### Which is true about the radius of a circle?

The radius is the distance between the centre and any point on the outer edge of a circle. This is the diameter of a circle that corresponds to the specified radius.

**What is the diameter of a straight line?**

The diameter of a circle is the length of a straight line drawn between two points on a circle where the line also passes through the centre of a circle, or any two points on the circle as long as they are exactly 180 degrees apart.
