Radius is half the diameter. 36/2=18

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

36 feet.

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.

Diameter is twice the radius, so 18 feet.

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

R=D/2. If the diameter of a circle is 18 inches, the radius is 9 inches. Radius = 1/2 diameter or 9"

A circle centre (0, 0) and radius r has equation x² + y² = r² The circle x² + y² = 36 has: r² = 36 → radius = 6
