What else can I help you with?
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 when the radius is r?
To find the circumference of a circle, use the equation: Circumference = 2*π*radius so when the radius is r, the circumference is 2πr
How do you find the radious of a circle can you find the circumference?
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
What is the approximate circumference of circle r?
Circumference of a circle with radius 'r' = 2(PI)(r) ~ 6.28(r)

What is the circumference when the radius is r?
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 circumference of a circle is about 31.4 what will the radius of the circle be?
circumference of circle= 2*3.14*radius 31.4=2*3.14*r r=5 app
How do you find the radious of a circle can you find the circumference?
The radius of a circle is the distance from its centre to its circumference. If a circle has a radius of r units then the length of its circumference is 2*pi*r units.
What is the approximate circumference of circle r?
Circumference of a circle with radius 'r' = 2(PI)(r) ~ 6.28(r)
If the circumference of a circle is 2053 feet what is the radius of the circle?
Given the circumference of a circle the radius is: r = C / 2xPI So the radius of your circle is 326.7451 ft
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!!!!!
Work out the radius of a circle from the circumference?
c=2*pie*r c= circumference r= 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.
What is the radius of a circle with a circumference of 22 units?
Circumference of the circle is 22 units. Circumference of the circle is 2*3.14(pi)*r S0, 2*3.14*r=22 r= 22/6.28 units.
What is the circumference of a circle if the radius is 4.83cm?
The circumference of a circle is given by the equation C=2*pi*r (r being the circle's radius). So, the circumference you're looking for is 30.35 cm.
