How do you find the radius of a circle if you know the radius?
You already know the radius.
How do you find the radius of the base in a cylinder?
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
How do you find the radius of the circle when you know the center and a point on the circle?
measure it
How do you find the radius and diameter of the circle if you know the area?
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
How do you find the radius if you do not know the diameter?
You can measure it. Otherwise, you certainly have to know SOMETHING about the circle to calculate the radius, usually the diameter, the circumference, or the area. If you don't know anything at all about a circle, you can't find out the radius, either.
The radius of a circle with a circumference?
R(10) If you know the Circumferance, divide it by Pi (about 3.14). That will tell you the diameter. Half the diameter equals the radius.

How do you find the diameter of a circle when you know the radius?
Diameter = 2*Radius
How do you find the radius of the circle when you know the center and a point on the circle?

How do you find the radius of a circle if you know the circumfrence?
radius = circumference/(2*pi)
How do you find the radius and diameter of the circle if you know the area?
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)

When you know the radius of a circle how can you find the area?
Area of a circle = pi*radius2
How do you find the radius of a circle if you dont know the circumference?
Well, if you know the diameter you divide that by two to get the radius.
How do you find the diameter of a circle if you know the radius?
Multiply by two. The diameter is twice the radius.
How do you find the radius of a circle if you only know the area?
Radius = +sqrt(Area/pi)
