Answer 1

@brainly...

Area of the circular lawn--154m²

πr²=154

22/7*r²=154

r²=154*7/22

r²=49

r=7

Circumference=2πr=2*22/7*7=44m

Hence the circumference of circular lawn is 44 metres

Answer 2

Step-by-step explanation:

A=

$\pi \times{r}^2$

22\7*r*r=154

r sq = 22*154/7

=r sq=484

r=22

c=

$2\pi \times r$

2*22/7*22

=138.28m
