Answer:

Given -:

\textsf{Radius of the sphere = 7cm}

 \sf{\pi =  \dfrac{22}{7} }

To find -:

The surface area of the the sphere .

Taken -:

To find surface area use this formula :

s =4 \pi \: {r}^{2}

Where,

s = Surface area

r = Radius

Concept -:

Just multiply the 4 and pi of the sphere with the square of the radius of the sphere.

Solution -:

\implies{s=4×\dfrac{22}{7}×(7²)}

\implies{s=4×\dfrac{22}{7}×(7×7)}

\implies{s=4×\dfrac{22}{7}×49}

\implies{s=4×22×7}

\implies{s=4×154}

\implies{s=616}

Answer -:

So , the surface area of the sphere is 616 .
