The diameter would be 14 cm, since the diameter is twice the radius.
No. diameter = 2 x radius ⇒ radius = diameter ÷ 2 If the radius is 14 ft the diameter is 2 x 14 ft = 28 ft If the diameter is 7ft the radius is 7 ft ÷ 2 = 31/2 ft.
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
14 cm
Diameter equal 2r (d=2r) So if your Diameter is 28 then: 28=2r (divide 2 on both sides) 14=r therefor the radius is 14
