Pie R squared, often denoted as πR², is a mathematical formula used to calculate the area of a circle, where R represents the radius. This formula is fundamental in geometry and is widely applied in various fields, including physics, engineering, and architecture, for tasks involving circular measurements. The area computed can be essential for determining material requirements, space utilization, and other practical applications related to circular shapes.

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
