Pi, is an irrational number (it cannot be written as a fraction) For this reason, 3 times pi is also irrational.

6pi = 18.85 (rounded)
Since pi is irrational, any multiple of it is too.
the same as pi squared, which is 9.86960440109

It is 2*pi/3.
The area of a circle is pi times radius times radius. 6 cm = 2 times 3 cm radius = 3 cm. SO, pi times 3 cm times 3 cm 9 pi pi is approximately 3.141592... 9 times 3.141592... is 28.274328...
3 times pi is an irrational number because it can't be expressed as a fraction
(pi + pi + pi) = 3 pi = roughly 9.4248 (rounded) Well, if you use the common shortened version of pi which is 3.14 and add that 3 times, you get 9.42.
Pi, is an irrational number (it cannot be written as a fraction) For this reason, 3 times pi is also irrational.
3*pi = 9.424777961 to nine decimal places.

No, it is not.
the formula is pi times r squared pi = 3.14 r = 3 3 squared = 9 so its 3.14 times 9
6pi = 18.85 (rounded)
The circumference C is pi times the diameter of the circle, which is twice the radiusC= pi *2rThe area A is pi times the radius squaredA = pi r2where pi = about 3.14159Example:For a radius of a 3 cmC = pi x (3 x 2) = pi x 6 = about 18.85 cmA = pi x (3)2 = pi x 9 = about 28.275 cm2
