The surface area of the sphere with the given radius is 113.04cm².
Sphere
A sphere is simply a 3-dimensional object with no vertices and edges.
The surface area of a sphere is expressed as;
Area = 4πr²
Given the data in the question;
- Radius of the sphere r = 3cm
To determine the surface area of the sphere, we substitute our given values into the expression above.
Area = 4πr²
Area = 4 × 3.14 × (3cm)²
Area = 4 × 3.14 × 9cm²
Area = 113.04cm²
Therefore, the surface area of the sphere with the given radius is 113.04cm².
