What is the radius of a circle if the circumference is 20.5?
Circumference = 2*pi*r r(radius) = Circumference/(2*pi) r = 20.5/6.283185307 = 3.26 ======
What is radius of a circle with a circumference of 7.07?
If the radius is r then the circumference is 2*pi*r So r -= circumference/(2*pi) = 1.13 units.
If a circle has a radius of cm what is the circumference?
Circumference = πd diameter = 2 x radius
How many times will the radius fit on the circles circumference?
The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. To determine how many times the radius fits into the circumference, you divide the circumference by the radius: ( \frac{C}{r} = \frac{2\pi r}{r} = 2\pi ). Therefore, the radius fits approximately 6.28 times around the circumference of the circle.
How do you find the circumference of a circle with just the radius?
The circumference of a circle is equal to the radius times 2*pi. 2*pi*R where R is the radius.

What is the equation for finding the radius of a sphere when you know the circumference?
The equation for circumference is C=2(pi)(r) where C is the circumference and r is the radius. You can find the radius by plugging in the circumference into this equation and solving the equation.

What is the equation for the circumference and radius?
The equation for circumference is 2(3.14)(r) or 3.14(d) where r=radius and d=diameter. The radius of a circle is half of the circumference, or the distance across the interior of a circle.
What is the relationship of the radius to the circumference?
The relationship is ; - Circumference equals two multiplied to 'pi' multiplied to the radius. Algebraically this is written as C = 2pir Since two radii (Note the spelling; NOT radiuses), equals one diameter. This can also be written as C = pi*d 'pi' is the Constant of Proportionality, and has the approximate value of 3.141592.... ( recurs to infinity as an irrational number. However, when learning circular calculations. pi will be given as 3.14, 3.1416 or 22/7 The other circular equation you need to know the the area of a circle. Area equals 'pi' multiplied to the radius squared. Algebraically, it is written as A = pi*r^(2). NB Only the radius is squared; NOT 'pi' . Hope that helps!!!!!
How do you find the circumference by the radius?
circumference equal 2*pi*r(radius) C=2PiR
What is the radius of a circle with a circumference of 1000m?
The radius of a circle with a circumference of 1000m is approximately 159.15 meters. This can be found using the formula C = 2πr, where C is the circumference and r is the radius. Rearranging the formula to solve for r gives r = C / (2π). Substituting the given circumference into the formula will give you the radius.
What is the circumference of a circle with the radius of 43?
Circumference = 2pi*r Circumference = 86pi
