Answer 2

Answer:

Hence, surface area of Sphere will be 616 Sq. cm

Step-by-step explanation:

In context to question asked,

We have to determine the surface area of the sphere.

As per question,

We have,

Radius of sphere = 7 cm

As we know that,

Sphere is a three dimensional figure.

The surface area of sphere can be determined by using formula,

$Area = 4 \Pi r^2$

So, for determining the surface area we will put the value of r given in the question in above formula,

Thus we will get,

$Area = 4 \Pi r^2\\=> 4 \times \frac{22}{7} \times 7 \times 7\\=>4 \times 22 \times 7\\=>616\:cm^2$
