What is the square inch of a 6 inch circle?

Answer 1

In other words, what is the area of a circle? The formula is

Ï€r2

pronounced 'pi r squared', and means the constant pi, which is multiplied by the radius squared. In your case, with 6 inch radius, the answer would be

πr2 = π62= 36π in2. Taking π = 22 / 7, we can say that: 36π in2= 113.14 in2.

The above math is wrong. You need to use the Radius of the six inch circle which is 3 inches, as well, 22/7 is a very rough estimate of PI as well, only good to 2 decimals.

pi*r2 in this case is pi*32=28.27in2 or 182.39cm2

Answer 2

28.27

Answer 3
