How do you find the circumference of a circle using the radius?
Circumference = 2*pi*radius So the radius = circumference/2*pi
Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
What is the radius of a circle whose circumference is 28?
pi = 3.1416 ( a constant) Circumference = 2 * pi * radius, so radius = circumference / (2 * pi) So radius = 28 / ( 2 * 3.1416 ) = 4.456 units
Calculate circumference with a radius of 2.250m?
Circumference of a circle = 2*pi*radius or pi*diameter. 2*pi*2.250 = 14.13716694 metres.
How do you find out the circumference of a circle?
Circumference = 2*pi*radius or diameter*pi
What is the circumference if the radius is 15 in?
Circumference = 2*pi*rCircumference = 2*pi(15 inches)= 94 inches========
What is the circumference of 15 cm?
Circumference of a circle = 2*pi*radius or diameter*pi
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 convert basic circumference into radius?
Circumference = 2*pi*radius Radius = Circumference/(2*pi)
What is the circumference if the radius is 15?
Radius = 15Diameter = 2 x radius = 30Circumference = pi D = 30 pi = 94.25 (rounded)
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 find a circumference of a circle if the radius is a fraction?
The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.The circumference is 2*pi*radius. It does not matter if the radius is an integer or a fraction.
How do you find radius with only the circumference?
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
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)
How do you find the radius if you the the circumference?
Circumference = 2 x Pi x Radius Radius = Circumference / (2 x Pi).
If the radius of a circle is tripled what happens to the circumference?
Circumference = pi x diameter so if the radius is 5 then the diameter is 10 Circumference = pi x 10 = 31.415 If we triple the radius to 15, then the diameter is 30, so Circumference = pi x 30 = 94.245 Which looks like triple the first circumference. So if the radius is tripled, the circumference is also tripled.
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*pi
