2.4 cm

The diameter of a circle is twice the radius

Thus a ring with radius 1.2 cm has a diameter of 2.4 cm

2.4cm

Since:

$2 \cdot r a d i u s = d i a m e t e r$ $2*radius = diameter$

The diameter of a ring with radius of 1.2cm is:

$2 \cdot 1.2 = 2.4$ $2*1.2=2.4$

Answer 3 · 2018-04-25T13:10:16

radius $r = 1.2 c m$ $r=1.2 cm$ , diameter $d = 2 \cdot r = 2.4 c m$ $d=2*r=2.4 cm$

diameter $d = 2 \cdot r = 2 \cdot 1.2 cm = 2.4 cm$ $d=2*r=2*1.2 " cm"=2.4 " cm"$

$2.4 c m$ $2.4cm$

$Diameter = 2 \times radius$ $"Diameter"=2xx"radius"$

Radius = $1.2 c m$ $1.2cm$

$therefore$ $-> "diameter"=2 xx 1.2=2.4cm$
