Question 580210
{{{A=pi*r^2}}} Start with the area of a circle formula.



{{{A=pi*(8)^2}}} Plug in {{{r=8}}}.



{{{A=(3.14)*(8)^2}}} Replace {{{pi}}} with {{{3.14}}} (note: Use more digits of {{{pi}}} to get better accuracy).



{{{A=(3.14)*(64)}}} Square {{{8}}} to get {{{64}}}.



{{{A=200.96}}} Multiply  {{{3.14}}} and {{{64}}} to get {{{200.96}}} (this figure is approximate).




So the area of the circle is roughly 200.96 square meters
