The radius of a circle is half of its diameter

1/2 of the diameter

The diameter of a circle is twice its radius. Thus the radius of a circle is half its diameter. → a circle with a diameter of 15 cm has a radius of 15/2 cm = 7.5 cm

The diameter of any circle is twice the radius.

7cm; the diameter of a circle is twice its radius.

It is 18 centimeters because your radius is exactly half of the diameter in any circle

36 feet.

Diameter is twice the radius, so 18 feet.

72, double the radius because radius is half of the whole diameter.

It's 18 cm. The radius is half the diameter of a circle. Half 36 cm is 18 cm.

The circumferecne of a circle with diameter d is pi*d So diameter = circumference / pi = 36/pi = 11.46 inches. Radius = diameter/2 = 5.73 inches.

The answer depends on what is 36 cm: the radius, diameter or some other aspect of the circle.

The radius is 18 inches (r = d/2).

circumference of a circle = 2*pi*radius or pi*diameter

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.
