The approximate surface area of the given sphere is 113.1 cm².
The given figure is a sphere with a radius of 3cm.
What is a sphere?
A sphere is a three-dimensional object where each point(lying on it) in space is equidistant from a fixed point called the centre of the sphere.
The surface area of a sphere with radius r is given by:
A=4πr²
So, the surface area of a sphere with a radius of 3cm will be:
A=4π(3)²cm²
A=36π
A=113.1 cm²
Hence, the approximate surface area of the given sphere is 113.1 cm².
