Answer:

Approximate surface area of the sphere is:

50.24 cm²

Step-by-step explanation:

We know that:

Surface area of sphere is given by 4πr²

Where r is the radius of the sphere

Here r=2 cm

Surface area=4×3.14×2²

                    = 50.24 cm²

Hence, approximate surface area of the sphere is:

50.24 cm²
