How can you use radius to find the diameter?
you double the radius to find the diameter.
How do you find diameter from radius?
diameter = 2*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.
How do you find the radius if the diameter is given?
the radius is half the diameter
How do you find radius when given a diameter?
The radius is half the diameter.
How do you find the radius of a circle from the diameter?
the radius is half the diameter
Can you find the diameter by doubling the radius?
Yes, the radius is half of the diameter, therefore the diameter is twice the radius.
How do you find the diameter if you have the radius?
The diameter is twice the radius. So multiply the radius by 2
How to find radius?
The radius of a circle is half of the diameter. Radius= Diameter divided by 2
How do you find the diameter and then the circumference if you have the radius?
Diameter = radius * 2 Circumference = pi * diameter.
How do you find the diameter of a circle when you know the radius?
Diameter = 2*Radius
How do you find a radius using the diameter?
Divide the Diameter by 2 to get the Radius
