It is 0.9 metres.
the diameter of a circle with the radius of 9m is 18m
What is the radius of a circle with a diameter of 4.56 m? The radius is half the diameter. Radius r = 2.28 m
Diameter: 2*9.5 = 19 m
The circumference of any circle is (pi) x (diameter),and of course, the diameter is double the radius.
11 m
Diameter = 2 x radius, so (3.9 m) x 2 = 7.8 m
The radius if the circle is half of its diameter and so 30/2 = 15 mm
21.4 m
Radius: 2.1 divided by 2 = 1.05 m
24 meters.The diameter is twice the radius.Both radius and diameter are straight lines. The radius extends from the center of the circle to any point on the circumference. The diameter extends from any point on the circumference through the center to the circumference on the opposite side of the circle.
radius is half diameter r = 1/2 x 24 = 12
That will depend on what is meant by 1.1 m if it's the radius of a circle then the diameter is 2*1.1 m = 2.2 m
