The radius of a circle is the distance from the centre of the circle to a point on the circumference of the circle.
If it is a drawing and the circle is to scale the radius can be measured with a ruler. If not, the radius can be calculated if the diameter, circumference or area of the circle is known.
the radius is equal to:
- the diameter divided by 2
- the circumference divided by 2pi(approx. 6.284)
- the square root of the area divided pi (divide by pi first, then take the square root)

If you only have the radius how do you find the height of a cylinder?
You can't find the height of a cylinder if you know the radious, because the radious only determines how many units the circle is around. so it's impossible to find the height of a cylinder if you only know the radious.
How t find the radious of an circle?
Ok i need help because i dont know
How do you find the radious of a circle can you find the circumference?
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
What is the circumference of a circle with radious of 6?
The circumference of a circle with radius of 6 is about 37.7
What word means a part of a circle?
Diameter, cord, radious.
