Question

the area of a circular Garden is 1386 m square. find the perimeter of the garden Pizzz its urgent am put in brainlist answer

Answer 1

SEE

AREA OF CIRCLE IS πR^2

NOW WE HAVE GIVEN IT ......
IS 1386 M2

SO 1386=πR2

=1386=22/7*R*R

=1386*7/22=R*R

=63*7=R*R

=441=R*R

=√441= R

SO R IS 21M

NOW WE HAVE TO CALCULATE JUST ITS CIRCUMFERANCE......

AND CIRCUMFERENCE OF A CIRCLE .=

=2πr

=2*22/7*21

=44/7*21

=44*3

=132

so the perimeter of that garden is 132m^2

I HOPE IT WILL HELP YOU......

IF YES PLZ MARK AS BRAINLIEST.....☺☺
