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 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 circumference of a circle with the radius of 43?
Circumference = 2pi*r Circumference = 86pi
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.
Work out the radius of a circle from the circumference?
c=2*pie*r c= circumference r= radius.
If a circle has a radius of cm what is the circumference?
Circumference = πd diameter = 2 x 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 radius of a circle if given the circumfrence?
The circumference (c) of a circle = 2πr (where r = radius). Therefore if you know the circumference, the radius (r) = c/2π.
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 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.
How do you find the circumference by the radius?
circumference equal 2*pi*r(radius) C=2PiR
What is the relationship of the radius to the circumference?
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
What is the circumference of a circle with the radius of 43?
Circumference = 2pi*r Circumference = 86pi
What is the radius of a circle that has the same area and circumference?
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.
