✔ 最佳答案
diameter is twice as radius : d= 2rso d = 12.4 cm
....2r = 12.4 cm
......r = 12.4 cm/2 = 6.2 cm

r = d/2
(radius = diameter/2)
12.4 cm
= 12.4 cm/2
= 6.2 cm
(radius = diameter/2)
12.4 cm
= 12.4 cm/2
= 6.2 cm

radius is always half of diameter. so 12.4 / 2 = 6.2
half of 12 is 6, and half of .4 is .2 ,
hence 6.2 cms is the radius
half of 12 is 6, and half of .4 is .2 ,
hence 6.2 cms is the radius

radius is alway half of diameter. then 12.4/2 = 6.2

Definition of a Diameter of a circle is 2 times its Radius
So 2*Radius = Diameter
Then Radius = 1/2 Diameter
Radius = 1/2 ( 12.4cm)
Radius = 6.2 cm
So 2*Radius = Diameter
Then Radius = 1/2 Diameter
Radius = 1/2 ( 12.4cm)
Radius = 6.2 cm

radius = diameter/2
so 12.4/2=6.2cm
so 12.4/2=6.2cm
