At around 1900 B.C., Egyptians estimated the value of pi to be 256/81.
22/7 or 3.142857...
The ancientsgave pia value of 3 which is wrong but even today we do not know its exact value only that it is the circumference of a circle divided by its diameter
If you mean "the value of pi rounded to the nearest hundredth," then: 3.14
First divide by (2 x pi) to obtain the radius. Then calculate the area with the well-known formula for the area of a circle: A = pi x radius2.First divide by (2 x pi) to obtain the radius.
