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.
