Answer 1

113.04 cm²

==========

The figure given is a sphere with a radius of 3 cm

formula for surface area of sphere : 4πr²

Solve:

⇒ 4πr²

⇒ 4(3.14)(3)²

⇒ 113.04 cm²

Answer 2

113.04 cm²

Solving it:

The SA given is 4πr²

To get your answer

First, you multiply these

4πr²

Add/ Plug-in the radius:

4(3.14)(3)²

And this is your answer:

113.04 cm²
