The given measure, 225*pi cm is a linear measure so it cannot refer to the area. It could refer to the radius or the circumference of the circles, or the length of an arc or a segment of the circle. It could, of course refer to something else, but then the task of finding the diameter is near impossible.
If it is the length of an arc or a segment, you require further information. Since that is not provided, perhaps one can assume that the measure does not refer to either.
That leaves the radius or the circumference. If the radius is 225*pi then the diameter is simply 2*radius = 450*pi cm.
If the circumference is 225*pi, then the diameter is circumference/pi = 225 cm.
circumference = pi*diameter So diameter = circumference/pi = 14*pi = 4.46 cm
The diameter of a circle if the circumference is 41 cm is about 13.05 cm (C divided by Pi = diameter)
The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2
pi*diameter =pi*6.5cm =20.42cm
pi*18 cm
Circumference of a circle in cm = diameter*pi or 2*pi*radius
Diameter in cm = circumference/pi
Circumference of a circle in cm = 2*pi*radius or diameter*pi
circumference = pi*diameter So diameter = circumference/pi = 14*pi = 4.46 cm
The formula to calculate the circumference of a circle is C = πd, where C is the circumference, π is approximately 3.14, and d is the diameter of the circle. If the diameter is 1 cm, then the circumference would be C = π(1) = 3.14 cm.
Diameter of the circle: 34/pi = 10.823 cm rounded
The diameter of a circle when the circumference is 35 cm is: 11.14 cm (circumference divided by Pi = diameter).
The diameter of a circle if the circumference is 41 cm is about 13.05 cm (C divided by Pi = diameter)
The diameter of a circle that has a 33 cm circumference is: 10.5 cm (circumference divided by pi = diameter).
The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2 The area of a circle with a diameter of 28 cm is pi*(d/2)2= 615.8 cm2
pi*diameter =pi*6.5cm =20.42cm
