Answer :
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.
