Find the surface area of a sphere of radius:(i) 10.5 cm (ii) 5.6 cm (iii) 14 cm

Explanation

To find the surface area of a sphere, we use the formula:

\[ \text{Surface Area} = 4 \pi r^2 \]

where \( r \) is the radius of the sphere.

Let's calculate the surface area for each given radius step by step.
