How many ft are in a circle with 27 ft circumference?

Firstly divide 27 by 3.14 to get the diameter. Then divide that by two to get the radius. Then square that and multiply by 3.14 to get the area. You get the following mathematical expression: [(27/3.14)/2]^2∙3.14 Firstly divide 27 by 3.14 which is approximately 8.6. The expression is now: [8.6/2]^2∙3.14 Now divide 8.6 by 2 which equals 4.3. The expression is now: 4.3^2∙3.14 Then square 4.3 which equals 18.49. The expression is now: 18.49∙3.14 That equals 58.0586. Threfore the area is 58.0586 ft^2 if pi is rounded to 3.14.
