How do you find the radius of a circle if you know the circumfrence?
radius = circumference/(2*pi)
How do you get the circumfrence of a circle?
divide
How do you find the radius when the circumfrence is given?
The circumference (not circumfrence!) is given by the equation C = 2*pi*r where r is the radius. So r = C/(2*pi) where pi is the irrational number that is approx 3.14159 or even more approximately, 3.14.
Circumfrence of a circle?
to fine the circumference of a circle you take the radius of a circle and multiply it by pi which is 3.14 even thoush there is a like a million other nunbers in pi you only multiply it by 3.14
How do you find the radius of circle with area 144pi?
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
How do you find the radius of a circle if you know the circumfrence?
radius = circumference/(2*pi)
How do you find the circumfrence of a circle with the radius?
two times the radius times pi
What is circumfrence and how do you find it?
The circumfrence is like a perimeter. It is the area around a circle. You can find the circumfrence of a circle by using this formula. Pi x R2 or Pi times the radius squared.
What is the circumfrence of a circle with a radius of 6?
18.84
How do you find the circumfrence of a circle when you have the area?
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
How do you find the radius of a circle if you don't have the area?
If you do not have the area, what do you have? The radius is half the diamiter The radius is PieR2 Worked backwards if you know the circumfrence.
What is the circumfrence of a circle with a radius of 11?
22*pi
How do you get the circumfrence for a circle?
Pi times radius squared.
Given a circle with a radius of 4 which is the circumfrence?
25.1
How do you find area and circumfrence of a circle?
It depends on what information you have: radius, diameter, lengths of tangents from a point outside the circle, length of chord and its distance from the centre, etc. Also, the term is circumference, not circumfrence.
What is the circumfrence of a circle with a radius of 5?
The circumference is about 31.415 units.
How Do you find the circumfrence when you know the radius?
Pi x the diameter of the circle will hive you the circumference. The diameter is double the radius so the answer to your question is pi2r.
