Answer:

A≈113.1

Step-by-step explanation:

The surface area of a given three-dimensional shape sphere with a radius of 3 is 113.4.

What is the surface area of a sphere?

A sphere is a three-dimensional shape analouge of a circle.

The area of a sphere = 4/3πr^3

It is given that the radius of a sphere is 3

The area of a sphere = 4/3πr^3

                                   = 4/3 × 3.14 × 3^3

                                   = 4 × 3.14 × 9

                                   = 113.4

Thus, the surface area of a sphere with a radius of 3 is 113.4.
