Question

If the diameter of a circular garden in the picture is 19.6 m, then find its area​

Answer 1

Diameter = 19.6 cm

Radius = 19.6/2 cm

Area = pi × r × r = 22/7 × 19.6/2 × 19.6/2 = 301.84 cm square

Answer 2

If the diameter of a circular garden in the picture is 19.6 m, then find its area.

$\mathtt{radius = \frac{diameter}{2}}$

$\mathtt {radius = 9.8m}$

$\mathtt {area \: of \: a \: circle = {r}^{2} sq \: units}$

$\mathtt{area = pie \: {r}^{2} sq \: units}$

$\mathtt \pink{area } \mathtt \green{ = } \mathtt \blue{301.34} \mathtt \red{ {m}^{2}}$
