It's 18 cm. The radius is half the diameter of a circle. Half 36 cm is 18 cm.
Diameter = 12 cm so radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 cm2
It is 18 centimeters because your radius is exactly half of the diameter in any circle
It depends on what the 6 cm refer to! The diameter of a shape with a 6 cm diameter is ... surprise!... 6 cm.
What is 36 cm as a fraction
The answer depends on what is 36 cm: the radius, diameter or some other aspect of the circle.
It's 18 cm. The radius is half the diameter of a circle. Half 36 cm is 18 cm.
36*pi
Perimeter = pi*diameter = 113.1 cm
Diameter = 12 cm so radius = 6 cm. Then area = pi*r2 = 36*pi = 113.1 cm2
It is 18 centimeters because your radius is exactly half of the diameter in any circle
Area of circle: 36*pi = 113.097 square cm to 3 decimal places
It depends on what the 6 cm refer to! The diameter of a shape with a 6 cm diameter is ... surprise!... 6 cm.
What is 36 cm as a fraction
Diameter = 17/pi cm
Diameter in cm = circumference/pi
radius 5 cm diameter 10 cm
