The radius of a circle is 1/2 of its diameter. If the diameter is 15 meters, then the radius is 7.5 meters.
radius = diameter/2
radius = 0.75/2 = 0.375
Diameter = Radius * 2 In this case, radius = 8 cm so diameter = 16 cm
Radius = 1/2 of diameter = 7/2 = 3.5 inches
Diameter of circle = 2 * Radius of the circle.
Radius = 1/2 diameter Radius = 7.5 ft = 7ft 6inches.
The radius of a circle is half the length of its diameter. Therefore, to find the radius of a circle with a diameter of 28 cm, you would divide the diameter by 2. So, the radius of the circle would be 28 cm divided by 2, which equals 14 cm.
Radius = Diameter/2 so if diameter = 20 Radius = 20/2 = 10
1/2 of the diameter
radius is halve the diameter. So d=375 r=375/2=187.5
Circumference of a circle = pi*diameter or 2*pi*radius
