2yd x 2 x pi = 12.566 yd
circumference of circle= 2*3.14*radius 31.4=2*3.14*r r=5 app
Radius = Circumference/(2*pi) = 10.98 cm
Divide the circumference by 2*pi because 2*pi*radius = circumference
Circumference = pi * 2 * radius, so with a radius of two meters, the circumference must be 12.56636... meters.
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
Circumference = 2*pi*r Circumference = 2*pi(14 yd) = about 88 yards (87.96 yards calculated, rounded to 2 significant figures).
radius of the circle = 11.32/(2*pi) = 1.802 yards rounded to 3 decimal places
The circumference of a circle with a radius of 2 is: 12.57 units.
It will have a radius of 2 because 2*pi*radius is the circumference of the circle.
Radius of a circle = circumference/2*pi
Use the formulae for the area and circumference of a circle, replacing the symbol for the radius or the diameter with the known radius or diameter. As a reminder, the radius is 1/2 the diameter.Circumference = pi x diameter area = pi x radius squared
The circumference of a circle if the radius is 2 feet is: about 12.57 feet.
2*pi*radius = perimeter or circumference of a circle radius = circumference/2*pi
Circumference of a circle = 2*pi*radius or diameter*pi
The ratio of the circumference to the radius of the circle is 2 times pi
For a circle, circumference = 2 x pi x radius.
Radius of a circle = circumference/2*pi
