To find the circumference of a circle, use the equation:
Circumference = 2*π*radius
so when the radius is r, the circumference is 2πr
If the radius is r then the circumference is 2*pi*r So r -= circumference/(2*pi) = 1.13 units.
Circumference = 2*pi*r r(radius) = Circumference/(2*pi) r = 20.5/6.283185307 = 3.26 ======
Circumference = πd diameter = 2 x radius
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.
The circumference of a circle is equal to the radius times 2*pi. 2*pi*R where R is the radius.
If the radius is r then the circumference is 2*pi*r So r -= circumference/(2*pi) = 1.13 units.
Circumference = 2*pi*r r(radius) = Circumference/(2*pi) r = 20.5/6.283185307 = 3.26 ======
c=2*pie*r c= circumference r= radius.
Circumference = πd diameter = 2 x radius
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.
The circumference of a circle is equal to the radius times 2*pi. 2*pi*R where R is the 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.
circumference equal 2*pi*r(radius) C=2PiR
circumference is the distance around a circle diameter is the distance from one point on the circle, straight across to the other side. radius is distance from the center of the circle to any point on the circle radius = r diameter = 2r circumference = 2(pi)r pi = 3.1415927
Circumference = 2pi*r Circumference = 86pi
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.
Circumference, C = 2*Pi*R Area, A = Pi * R^2 A = C Pi * R^2 = 2*Pi*R --> solve for R (radius) R = 2 So, the radius of a circle with area = circumference is two.
