The radius of a circle is 10 m. Find its area to the nearest whole number.


\dashrightarrow\large\textsf{\textbf{\underline{Answer and how to solve:-}}}

We're asked to find the area of the circle, which we can find using the following formula:-


\bold{Area_((circle))=\pi r^2}

Where:-

  • π = pi [3.14...]
  • r=radius (10 m)

What we need to do to find the area:-


\dagger Substitute 10 for r and 3.14 for π:-


\hookrightarrow\sf{A=3.14*(10^2)}


\bigstar On simplification,


\bold{A=3.14*100}


\bigstar On further simplification,


\bold{A=314}


\bigstar The Area is:-


\bold{A=314\:m^2}


\square\!\!\!\!\!\!\bigstar Note:- Area is always measured in units² (units squared)

Good luck with your studies.
