What is the name of hafe a diamter?
The name of half a diameter is a radius.
What is the diamter of a circle with a 3 in radius?
6 in.
When the diamter is 24 what is the radius?
The radius is half the diameter. Just divide the diameter by 2.
What is the radius of a circle if you only know the perimeter?
Divide the perimiter, or circumference, by pi (3.1415), which is the diamter, then divide that by 2 to get the radius
What is the formula for finding the radius when you only have a diameter?
diamter=2xradius, so if you have the diameter, divide by 2 and you have the radius. r=d/2
What would be the radius of a circle ith a diamter of 8 inches?
The radius is 1/2 the diameter. So, since the diameter is 8 the radius of the circle would be 4.
Diameter radius circumference pi?
Circumfrence=Pi x Diamter=Pi x 2Radius
How do you find the raduis of a circle whose diamter is 20?
Radius = Diameter/2 so if diameter = 20 Radius = 20/2 = 10
What is the volume if the raduis is 6 and the diamter is 11?
The question does not make sense on several levels.Raduis and diamter are not real words.If they are meant to be radius and diameter, then a radius of 6 is inconsistent with a diameter of 11 for any regular shape.If the shape is not regular, then a lot more information is required.
When you are given pi of a circle how do you find the radius and diameter?
you cant: pi is the same for any circle - 3.1415... the diamter or the radius has to be given diameter divided by two equals the radius the radius times two equals the diameter
What is the size of the CD?
a CD is 120mm (4.7 inches) in diameter and 60mm radius, the hole is 15mm diamter (0.6 inches).
What is the formula of finding the surface area of a circle?
This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.This is normally expressed in terms of the radius: area = pi x radius2.
