Answer 1

Answer:

ज आ धड़कन डच जब गद दखल दत्त तर

Answer 2

$\huge\fcolorbox{red}{cyan}{Diameter=4.2\:m}$

Step-by-step explanation:

• Surface Area = 55.44 m²

• Radius = ?

$= > \bf \color{red}{surface \: area = {4} \times \pi \times {r}^{2} } \\ = > {4} \times \frac{22}{7} \times {r}^{2} = 55.44 \\ = > \frac{88}{7} \times {r}^{2} = \frac{5544}{100} \\ = > \frac{88}{7} \times {r}^{2} = \frac{1386}{25 } \\ = > {r}^{2} = \frac{1386}{25} \times \frac{7}{88} \\ = > {r}^{2} = \frac{441}{100} \\ = > {r} = \sqrt{ \frac{441}{100} } \\ = > r = \frac{21}{10} \\ = > \boxed{r = 2.1}$

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Now Lets Calculate The Diameter :-

=> Diameter = Radius x 2

=> 2.1 x 2

=> 4.2 m
