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.

What is the diameter of a circle if the circumference is 41 cm?
The diameter of a circle if the circumference is 41 cm is about 13.05 cm (C divided by Pi = diameter)
What is the area of a 28 cm circle using pi?
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
What is the circumference of a 6.5 cm diameter circle?
pi*diameter =pi*6.5cm =20.42cm
What is circumference of a circle if a diameter is 18 cm?
pi*18 cm
What is the diameter of a circle if the circumference is 14 cm?
Well, honey, if the circumference of a circle is 14 cm, then we can use the formula C = πd to find the diameter. Plug in the given circumference and solve for the diameter. So, the diameter of the circle would be approximately 4.45 cm. Hope that clears things up for you, sugar!
