just use the area formula ex...
area of circle= pi(r square)
if you know what your area is then plug it in then do PI / by area that will be your diameter to get the radius / your answer by 2

How do you find the radius of the circle when you know the center and a point on the circle?
measure it
Is the point on the center of a circle a radius?
The radius is the line from the center of a circle to its circumference.
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.
How do you find diameter when you have the radius?
The diameter of a circle is simply twice the radius of the circle. The radius is a line that starts from the center of the circle to the circumference of the circle. The diameter is a line that passes through the circle. diameter=2xradius
What is the radius center circle in soccer?
The radius of the center circle is 9.15 mts. (10yds)
How do you get a radius?
# Find the center of the circle # Draw the line of the radius from the center to the circumference # Finish
How do you find the radius of the circle when you know the center and a point on the circle?

Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
Is the point on the center of a circle a radius?
The radius is the line from the center of a circle to its circumference.
If you know the length of a radius of a circle how can you find the length of the diameter?
The diameter of a circle is 2 times the radius. The radius of a circle is the distance from any point on the circle to the center of the circle, and the diameter is the distance from one side of the circle to the opposite side, passing through the center.
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.
How do you find diameter when you have the radius?
The diameter of a circle is simply twice the radius of the circle. The radius is a line that starts from the center of the circle to the circumference of the circle. The diameter is a line that passes through the circle. diameter=2xradius
What is the radius center circle in soccer?
The radius of the center circle is 9.15 mts. (10yds)
Which term describe the distance from the center of a circle to any point on the circle?
The distance from the center of a circle to any point on the circle is called the radius of the circle. The radius is a line segment that starts at the center of the circle and ends at any point on the circle. It is always a straight line and is always perpendicular to the circumference of the circle. The radius is half the diameter of the circle, which is the distance across the circle through the center. The diameter of a circle is always twice the length of the radius.

How do you find the diameter of a sphere?
R (radius) X2. The radius is half the circle from the center of the circle. The diameter is just straight across.
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
Find the radius of a circle which has a diameter of 3.6cm?
The radius of a circle is the distance from the center to an outside edge of the circle. The diameter is the distance all the way across the circle. Therefore, the radius is half the value of the diameter.
