Question

the area of a circular lawn is 154m2 find its circumfre

Answer 1

Answer:

44 m

Step-by-step explanation:

Given that

Area of the circular lawn =154 m^2

But area of the circular lawn = πr^2

So

πr^2 = 154

r       =  7 m

Now

Circumference of the lawn = 2πr

                                             = 2(22/7)(7)

                                              = 44 m
