Find the radius of a circle if its area is 254.5 square inches?

The formula for the area of a circle is pie r squared

therefore if pie r squared = 254.5

r squared = 254.4 divided by pie

= 81.009...

r = square root of 81.009...

= 9.000...

= 9 ( correct to the nearest whole number)

therefore radius of this circle is 9
