How do you figure out the radius if you only have length and width?
radius = diameter/2 radius = circumference/2*pi
If given the length of arc and the radius how do you figure the straight line cord?
The radius is a cord, is it not?
How do you figure out the circumference of something without knowing the diameter?
If you know the radius, double that to get diameter. If you have neither radius or diameter, then measure around the outside.
Is the length of the diameter always equal to the length of the radius?
The length of the diameter is always twice the length of the radius.
How do you figure the length of an arc?
If you know the radius and the angle (in radians) then r*x where r = radius, x = angle. If the angle is in degrees, then pi*r*x/180 Otherwise you have to measure it.

The radius is a cord, is it not?
How do you figure out the volume in a pipe?
pi × r2 × L (r=radius, L=length)
How do you figure out the diameter of a circle?
Pi times the radius of the circle squared = area And diameter is simply the radius x 2, since the radius is half the length of the circle.
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 regular polygon has a side the same length as it's radius?
Assuming that radius would be the length from any vertex to the center of a figure, a regular hexagon. It can be divided into six congruent equilateral triangles.
What is the radius and diameter if the area of a circle is 81 square units?
pi*radius squared = 81 square units Divide both sides by pi and then square root both sides to find the value of the radius. radius = 5.077706252 or 5 units in length to one significant figure 2 times radius = diameter = 10 units in length
The length of a radius is how many cm the length of a diameter?
The length of a radius is half the length of a diameter.
How do you figure out the circumference of something without knowing the diameter?
If you know the radius, double that to get diameter. If you have neither radius or diameter, then measure around the outside.
Is the length of the diameter always equal to the length of the radius?
The length of the diameter is always twice the length of the radius.

If you know the radius and the angle (in radians) then r*x where r = radius, x = angle. If the angle is in degrees, then pi*r*x/180 Otherwise you have to measure it.
What is the ratio of the length of the diameter of a circle to the length of its radius?
Length of diameter:length of radius = 2:1
