Question

a circumference of a circular flower bed is 132 m.find its area

Answer 1

circumference of a circular = 2πr

132 =6.28r

r=132/6.28

r=21

area of circle=πr^2

=3.14×21×21

=1384.74m^2

Answer 2

$circumference \: of \: a \: circular \: blower \: bed \\ = 2\pi \: r \\ r = \frac{132}{6.28} \\ = r \: = 21 \\ area \: of \: a \: circle = \pi \: r \\ = 3.14 \times 21 \times 21 \\ = 1384.74 m^{2} ans.......$

hope helpful for you...........
