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
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.
Diameter of circle = 2 * Radius of the circle.
Radius = 1/2 diameter Radius = 7.5 ft = 7ft 6inches.
Radius = Diameter/2 so if diameter = 20 Radius = 20/2 = 10
radius is halve the diameter. So d=375 r=375/2=187.5
1/2 of the diameter
Circumference of a circle = pi*diameter or 2*pi*radius
