Question

the area of a circular plot is 3850 square metres what isvthe circumference of the plot

Answer 1

Area of plot =πr²

Here, 3850=(22*r²)/7

3850*7/22 =r²

1225=r²

√{1225} =r

35=radius


Then,

Circumference of plot =2πr

Circumference of plot =2(22*35)/7

Circumference of plot =2*22*5

Circumference of plot =44*5=220m


I hope this will help you

Answer 2

$\pi {r}^{2} = 3850$
so

$22 \div 7 \times {r}^{2} = 3850$
${r}^{2} \div 7= 175$
${r}^{2} = 1225 \\ \\ r = 35$
then circumference will be
$2\pi \times r = 2 \times 22 \div 7 \times 35 \\ \\ circumference \: will \: be = 220m$
