Answer 1

Step-by-step explanation:

implantation of the fertilised egg occurs explain how the embryo gets nourishment inside the mothers body

Answer 2

circumference of circle =2πr

2πr=31.4

2x3.14xr=31.4

6.28xr=31.4

$r = \frac{31.4}{6.28}$

r=5 cm

$area \: of \: circle = \pi {r}^{2}$

$= 3.14 \times( {5})^{2}$

$= 3.14 \times 25$

$= 78.5 {cm}^{2}$
