Sagot :
Area
——————————————————————————
It's a pond then the solution is finding area of a circle.
Use this formula to get the area of circles using Radius [tex]\fcolorbox{black}{lime}{A = πr²}[/tex] meaning of ( π ) is pi or 3.14, while ( r ) is radius then ( ² ) it's meaning is times the number 2 times by its self.
Solution:
- [tex]\bold{A = πr²}[/tex]
- [tex]\bold{A = ( 3.14 )( 4.5m² )}[/tex]
- [tex]\bold{A = ( 3.14 )( 20.25m² )}[/tex]
- [tex]\bold{A = ( 63.585m² )}[/tex]
Step_by_step Explanation:
➣ A radius times by its self to times then the equal multiply it to pi or 3.14.

Formulas of Circles.
- ( Diameter ) D = 2 × r
- ( Circumference ) C = 2 × π × r
- ( Area ) A = π × r²
