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
How do you find out the circumference of a circle?
Circumference = 2*pi*radius or diameter*pi
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.
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)
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
What is the circumference if the radius is 15?
Radius = 15Diameter = 2 x radius = 30Circumference = pi D = 30 pi = 94.25 (rounded)
How do you find radius with only the circumference?
Circumference = 2*pi*radius So Radius = Circumference/(2*pi)
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 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).
How can you find the diameter and the radius if the circumference is given?
Diameter = circumference/pi Radius = circumference/2*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.
