No, it is not.
It is pi x 15 x 15 = pi x 225 = 3.1415 x 225 = 706.84 square cms
Area of the circle = pi R2 = (225 pi) square feetVolume = (225 pi) x (0.25) cubic feet1 cubic yard = 27 cubic feetVolume = (225 pi) / (4 x 27) = 6.545 cubic yards (rounded)
That symbol is used for a number, which is approximately 2.718. It is one of the most important numbers in mathematics, together with pi - both appear over and over again, in many places. The number "e" is the base of the natural logarithms.
Pi is not a natural number. Natural numbers are just the regular set of numbers used for counting (1, 2, 3, 4, ...). Pi, being not even a whole number, is not natural.

pi * 225/4 Radius is 15/2 pi r2 = pi * (15/2)2 = pi * 225/4
pi*radius2 = 225*pi Divide both sides by pi and then square root both sides: radius = 15 units of measurement
Area = pi x radius squaredradius = sq rt of 225 pi/pi =15C = 2pi x r = 30 pi
1 Any number over itself equals to one
pi
No, it is not.
Pi minus 2, Square root of 3, fourth root of 8, Natural Log of 7, e (base of natural logs), pi squared,.... There are an infinite number of them.

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.
