Question

the area of a circular Field is 5041pi metres square find the perimeter of a circular field

Answer 1

hello users .....

we have given that :
area of circular field = 5041π m²

we have to find :
perimeter of circular field = ?

solution :-
we know that :-
area of circle = πr²    ( r is the radius )
and 
circumference of circle = 2πr

now 
here,
area = 5041 π

=> πr² = 5041 π

=> r² = 5041 

=> r = 71 m 

now 
circumference = 2π r 
= 2 × 3.14 × 71 

= 445.88 m answer
