Circumference : 132cm

Area :?

circumference of circle = 2πr

132 = 2×22/7×r
132= 44/7×r

132×7=44×r

924/44=r

21 = r

Therefore radius of circle is 21

Now area of cirlcle is πr^2

22/7×21×21

=22×21×3

=1386m^2

Therefore area of circle is

1386m^2

Answer 2

Circumference = 132 m

=> 2πr = 132

=> 2 × $\frac{22}{7}$ × r = 132

=> r = 132 × $\frac{7}{44}$

=> r = 21 m

therefore, area = π${r}^{2}$

= $\frac{22}{7}$ × 21 × 21

= 22 × 3 × 21

= 66 × 21

= 1386${m}^{2}$
