Divide the circumference by Pi (3.14159), and that will give you the diameter. Divide that number by 2 to find the radius.

A circle has a radius of 12 in Find the diameter of the circle?
diameter is 2 times the radius 24
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.
Formula for the radius of a circle?
Well to find the radius it is diameter/2.
How do you find the radious of a circle?
The radius of a circle is any straight line from the centre of the circle to its circumference. The radius can also refer to the length of this line.
How do i find circumference and area of a circle?
Circumference of a circle = 2*pi*radius or diameter*pi Area of a circle = pi*radius squared
How do you find a circumfernce with a radius?
Circumference of a circle = 2*pi*radius or pi*diameter.
How do you find the diameter of a circle with the circumfernce size?
Divide the circumference by pi (~3.14) to get the diameter.
How to find the circumference of a circle?
It would be the radious squared times pi R2xpi (3.14) * * * * * The text is wrong, the formula is correct. The circumfernce is 2*π*radius or, since the diameter is double the radius, circumference = π*d π is an irrational number which is approximately 3.14
If a circle has a circumference is 5pi millimeters how do you find the area of the circle show your work also i do not have the radius or any other info?
Circumfernce = 5*pithat is, circumference = pi*d = 5*pi where d is the diameter.Therefore, circumference = 5 millimetres and so radius = d/2 = 2.5 mm.Now that the radius is known, area = pi*r^2 = 19.6 mm^2.
How do you find the radius of a circle with the circumference in terms of pi?
find the radius of a circle with circumference of 42.1
How do you find the radius of a circle if you already have to circumfernce?
the formula for the circumference is... C = 2 * (3.14159) * r (r in this equation is the radius) since you know what your circumference is all you do is put it on the left side of the equation for C. then you divide both the 2 and 3.14159 on both sides and then you have only r on the right side and you have your answer.
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 director circle of circle?
The director circle of a circle with radius r is a concentric circle with radius r*sqrt(2).
How do you find the radius of a circle if you know the radius?
You already know the radius.
How do you find the circumfernce of a circle with pi if the diameter is 3.5?
Circumference = 2Пr = 2 x 3.14159 x 3.5/2 = 10.995565
How do you find distance if radius is given?
Diameter of a circle = 2*radius Circumference of a circle = 2*radius*pi
How do you find what a diameter of a circle is?
It is twice the radius of a circle
