Help with area of shape

Introduction of solve find area of shape:
Area is a quantity expressing the two-dimensionals size of a defined part of a surface, typically a region bounded by a closed curve. The surface areas of a 3-dimensional solid is the total area of the exposed surface, such as the sum of the areas of the exposed sides of a polyhedron. Area is an important invariants in the differential geometry of surfaces

Example Problems of Solve Find Area of Shape:
Example 1:
Find the surface area of sphere with radius 8.7 meter?
Solution:
Step 1: Surface area of sphere = 4 pi radius 2.
Step 2: We know that radius = 8.7 m.
Step 3: Plug the radius value into the formula. This could also help us on angle of refraction
Step 4: Volume of sphere = 4 3.14 8.7 8.7
Step 5: So, we get 950.66 m2.
