Half it and so 22/2 = a radius of 11 inches
radisus: 11; diameter:22 (2X11)
2 X 11
Radius = Diameter/2 Diameter = 2* Radius
A radius is one half of a diameter so divide by two to get from a diameter to a radius. Or you can multiply the radius by 2 to get to the diameter.
The diameter is twice the radius (always). So the diameter will be 22.
Diameter = 2*Radius So, in this case, diameter = 44 cm
22
Half it and so 22/2 = a radius of 11 inches
22/3.1416=diameter /2
radisus: 11; diameter:22 (2X11)
The diameter is 4.4 cm
R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"
2 X 11
11 cm
47.14285714285714 radius = 1/2 of diameter radius=7.5 which is half of 15 using circumference of circle formula (2 * by pi * by radius) pi=22/7 2*22/7*7.5=47.14285714285714
Radius = Diameter/2 Diameter = 2* Radius
