# What is the relation ship of radius to diameter?

The relationship is that the radius is half of circle's diameter.

### What is the Relation between radius and diameter'?

The diameter of a circle is twice its radius.

### What is the relation between radius and diameter?

Radius = 1/2 of the diameter. Diameter = 2 times (double) the radius.

### How do you get the diameter from the radius?

to get the diameter from the radius you simply multiply the radius by 2 since the radius is half the diameter. d=2r where d = diameter and r = radius

### What is the diameter of a circle if the radius is 27 cm?

When you have the radius of a circle and you are trying to find the diameter, multiply the radius by two; the answer is the diameter. If you have the diameter and want to find the radius, divide the diameter by two; the answer will be the radius. The diameter is 54 centimeters.

### What is the Diameter to a radius of a circle?

A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.

### What is the relation between area of a sector and length of an arc of a circle?

There is no direct relation between the area of a sector and the length of an arc. You must know the radius (or diameter) or the angle of the sector at the centre.

### If the radius of a circle is six inches then the diameter is how many feet?

The diameter of a circle is twice the radius. The diameter of a circle is twice the radius. The diameter of a circle is twice the radius. The diameter of a circle is twice the radius.

### How do you get from diameter to radius?

The radius of a circle is equal to half of it's diameter. To convert the diameter into the radius, simply divide it by two. For example: if the diameter is 10, then the radius would be 5

### How do you calulate radius into diametre?

the radius is one-half the diameter radius = diameter/2 diameter = 2 x radius

### What is radius if diameter is 8?

The radius is half the diameter. So, if the diameter is 8, then the radius is 4.

### What is the diameter of a circle with a radius of 8 centimeters?

The diameter is double the radius, and the radius is 1/2 of the diameter. If the radius is 8 cm, then the diameter is 16 cm.

### If the radius of a circle is 20 what is the diameter?

The radius is 1/2 of the diameter, so if the radius is 20 units then the diameter is 40 units. You multiply the radius by 2 to get the diameter.

### What is the diameter of a circle whose radius is 4cm?

radius=4cm diameter=8cm *radius is half the diameter

### What is the diameter of a radius of 2.6?

Diameter = 2*radius so radius = 2.6 means diameter = 5.2

### What is the radius if the diameter is 4.4?

If the diameter is 4.4 the radius is 2.2 because to get the radius you divide the diameter by 2.

### How do you determine the radius if you only have the diameter?

to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !

### Can you find the diameter by doubling the radius?

Yes, the radius is half of the diameter, therefore the diameter is twice the radius.

### What the radius of a circle with diameter d 61 yd?

The radius of a circle is equal to half of it's diameter. If you want to figure out the radius from a given diameter, simply divide the diameter by two: Radius = Diameter / 2 Radius = 61 / 2 Radius = 30.5 yd

### What is the relationship between the radius and the diameter of a circle?

The relationship between the radius and the diameter of a circle is that: radius = diameter /2

### What is the diameter of a circle with a 7 inch radius?

The radius is half of the diameter. So, if the radius is 7 the diameter is 14.

### The length of a radius is the length of a diameter?

The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.

### What is the diameter of a circle with a 4.2 cm radius?

Diameter is twice the radius, therefore 4.2cm radius = 8.4cm diameter.

### What is half of a diameter?

The diameter of a circle is twice the radius. A radius is half of a diameter.

### What is the diameter of a circle and the radius is 6.8 yards?

The radius is half of the diameter. The diameter is double the radius. Diameter = 2 x 6.8 = 13.6 yards

### What is the diameter of a circle if the circumference is 23?

diameter = 7.32 Formula: Circumference = 2 * pi * radius 23 = 2 * (3.1416) * radius 23 = 6.2832 * radius 23/6.2832 = 6.2832/6.2632 * radius 3.66 = radius diameter = 2 * radius diameter = 2 * 3.66 diameter = 7.32

### What is the radius of a circle if the diameter is 14in?

The radius of a circle is half of the diameter, so the radius of a circle with a diameter of 14in is 7in.

### What has the greater uncertainty the diameter or the radius?

The diameter is always going to be twice the radius. The radius is always going to be half the diameter.

### What is the diameter of a semicircle with a radius of 5 ft?

Radius is = to half the diameter so.... when the radius of the semicircle is 5ft then the diameter is 10ft.

### What is the diameter and radius of a circle if the circumference is 37.68?

The diameter and radius of a circle if the circumference is 37.68 are: Diameter = 11.99 Radius = 5.997

### If the radius of a circle is 2.5 inches what is its diameter?

The diameter is twice the radius so a circle with a radius of 2.5 will have a diameter of 5.
