The diameter is twice the radius ! Therefore the answer is 19cm !
If a circle has a diameter of 19cm the circumference is: 59.7 cm
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
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
diameter = 2*radius
The diameter is twice the radius ! Therefore the answer is 19cm !
If a circle has a diameter of 19cm the circumference is: 59.7 cm
A circle with a radius of 19 cm has an area of 1,134.11 square cm.
Radius = Diameter/2 Diameter = 2* 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
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.
The length of a radius is not the length of a diameter. The diameter is two times the length of the radius.
radius = diameter/2
The radius is half the diameter. So, if the diameter is 8, then the radius is 4.
A radius is half of a diameter. Example Diameter:4 Radius:2
The diameter of a circle is twice its radius.
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.
