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 of a circle if you know the circumferance?
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)
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.

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)
How do you find the center of a circle if you know the radius?
the radius is half of the diameter. and the middle of the circle is half way between this diameter.
