Answer 2

Answer:

$\purple\mapsto\sf{Formula \: Used:-}$

$\mapsto\sf\purple{Surface \: Area \: of \: Sphere =}\sf{ {4\pi \: r}^{2} }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \:$

$\purple\mapsto\sf{Solution:-}$

$\mapsto\sf\purple{Diameter =} \sf{ 14}$

$\mapsto\sf\purple{Radius =} \sf{ \frac{ Diameter }{2}}$

$\mapsto\sf\purple{Radius =} \sf{ \frac{ \cancel14 }{ \cancel2}}$

$\mapsto\sf\purple{Radius =} \sf{ 7}$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \:$

$\mapsto\sf\purple{Surface \: Area \: of \: Sphere =}\sf{ {4\pi \: r}^{2} }$

$\mapsto\sf\purple{Surface \: Area \: of \: Sphere =}\sf{ {4 \times \frac{22}{ \cancel7} \times \cancel7 \times 7</strong><strong> </strong><strong>} }$

$\mapsto\sf\purple{Surface \: Area \: of \: Sphere =}\sf{4 \times 22 \times 7</strong><strong> </strong><strong> }$

Surface Area of Sphere = 616
