unless you know the value of x you cant solve it so its just 4(pie)x "Pi" is just a number. The product of 4 times (pi) times 'x' depends on the value of ' x ', and it changes immediately as soon as the value of ' x ' changes.
the same as pi squared, which is 9.86960440109
The area of the circle becomes 9 times the area of the original circle. Original circle = Pi * (r ^ 2) = Pi * r * r New Circle = Pi * ((3 * r) ^ 2) = Pi * 9 * r * r
You either keep it as "89 pi" to have the exact value, or you take the desired number of decimals for pi (depending on the desired precision), for example 3.14, or 3.1416, and then multiply.
circumference=pi circumference=pi circumference=pi
I Think the value of pi is 3.1416 ...
In ancient times the value of Pi was given as 3 but even today the exact value of Pi is not known because it is an irrational number.

9 and 3 are in the 14th and th decimal place for the value of pi.
The value of pi is an irrational number. Pi is the ratio of the circumference of a circle to the circle's diameter. Also, π is a transcendental number.
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...
The average value of pi is a very small number, 3.14 to be precise, but that value od pi is when it is not extracted and stretched millions of times. Scientists are puzzled as to what the value of pi actually is, but 3.14 is more than enough for children in schools.
No because the value of pi as regards to a circle is an irrational number
3.142
Pi times pi equals 9.869604401089358 (to 15 decimal places).The square value 9.8696 is commonly used.If you use (pi)2 = 10 in your calculations, your answer is only wrong by about 1.3% .
