The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. If the radius is 2, then the circumference is ( C = 2\pi \times 2 = 4\pi ). Therefore, the circumference is approximately 12.57 units when using ( \pi \approx 3.14 ).

If the circumference of a circle doubles the radius?

IMPOSSIBLE circumference = 2*pi*radius if circumference = 2*radius: 2*radius=2*pi*radius 2*radius/(2*radius)=2*pi*radius/(2*radius) 1=pi pi= 1 therefore it is impossible to have a circumference that is twice that of the radius


How do you convert basic circumference into radius?

Circumference = 2*pi*radius Radius = Circumference/(2*pi)


How do you find a circumference of a circle if the radius is a fraction?

When given radius how do you find the circumference?

Circumference = 2 * radius * pi (where pi is approx = 3.14159)So Radius = Circumference / (2 * pi)


How do you find radius with only the circumference?

Circumference = 2*pi*radius So Radius = Circumference/(2*pi)


Radius from circumference?

The radius is 1/2 of the circumference.


How do you find the radius if you the the circumference?

Circumference = 2 x Pi x Radius Radius = Circumference / (2 x Pi).


What is the radius of a circle if the circumference is 4pi?

It will have a radius of 2 because 2*pi*radius is the circumference of the circle.


What is the radius if circumference is 25.12?

circumference = 2 × π × radius → radius = circumference ÷ (2 × π) = 25.12/(2π) ≈ 4 units


How do you work out the area if given the circumference?

Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)Assuming the shape concerned is a circle, Radius = Circumference/(2*pi)and thenArea = pi*(radius)2= pi*(circumference)2/(2*pi)2= (circumference)2/(4*pi)


What happens to the circumference of a circle if youndouble the radius?

Circumference = 2 x π x radius double radius: new_circumference = 2 x π x (radius x 2) = (2 x π x radius) x 2 = circumference x 2 → if the radius is doubled, the circumference is doubled.


If you divide the circumference by 2 is that the radius?

No. Circumference is piRADIUS2. but if you divide diameter by 2 that is the radius.
