Question 530880
If the diameter of a circle is 27 meters, then the radius is 27/2 = 13.5 meters



So r = 13.5



{{{A=pi*r^2}}} Start with the area of a circle formula.



{{{A=pi*(13.5)^2}}} Plug in {{{r=13.5}}}.



{{{A=(3.14159265)*(13.5)^2}}} Replace {{{pi}}} with {{{3.14159265}}} (note: Use more digits of {{{pi}}} to get better accuracy).



{{{A=(3.14159265)*(182.25)}}} Square {{{13.5}}} to get {{{182.25}}}.



{{{A=572.5552604625}}} Multiply  {{{3.14159265}}} and {{{182.25}}} to get {{{572.5552604625}}} (this figure is approximate).



{{{A=572.6}}} Round to the nearest tenth.



So the area is roughly 572.6 square meters.
