It's 18 cm. The radius is half the diameter of a circle. Half 36 cm is 18 cm.
It is 18 centimeters because your radius is exactly half of the diameter in any circle
Diameter = 12 cm so radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 cm2
The radius is always exactly half of the diameter, so if the radius is 8 cm, then the diameter is 16 cm.
it is half the diameter e.g 10cm diameter = 5 cm radius
It's 18 cm. The radius is half the diameter of a circle. Half 36 cm is 18 cm.
The answer depends on what is 36 cm: the radius, diameter or some other aspect of the circle.
It is 18 centimeters because your radius is exactly half of the diameter in any circle
diameter = radius × 2 → radius = diameter ÷ 2 = 10 cm ÷ 2 = 5 cm
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
radius 5 cm diameter 10 cm
Diameter = Radius * 2 In this case, radius = 8 cm so diameter = 16 cm
If the diameter is 12 cm the radius is 6 cm.
The diameter of a circle is double the radius. So a circle with a radius of 7 cm has a diameter of 14 cm.
The diameter would be 14 cm, since the diameter is twice the radius.
Diameter = 12 cm so radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 cm2
it is half the diameter e.g 10cm diameter = 5 cm radius
