17

The diameter of any circle, including that one, is double (two times) its radius.

It is 17/2 = 8.5 cm.

The diameter of a circle is twice its radius

The radius of a circle is half the diameter so if the radius of a circle is r, then the diameter is 2r.

Diameter = 2 times the radius = (2 x 8.5) = 17 cm

The diameter of any circle, including that one, is double (two times) its radius.

17 cm

The radius measures from the center of the circle to the perimeter (outside), so if the radius is 8.5 cm that would make the diameter of the circle 17 cm. (8.5 cm X 2 = 17 cm)

It is 17/2 = 8.5 cm.

The diameter of a circle is twice the length of the radius. Therefore, if the radius is 4.2 cm, the diameter would be 2 x 4.2 cm = 8.4 cm.

The radius of a circle is always half of the diameter. If the diameter is 85.4, the radius is 42.7.
