How to Find the Surface Area of a Sphere Calculator?
The surface area of a sphere is the number of unit squares that can be fit into it and it is measured in square units. The surface area of a sphere is calculated by the following formula:
The surface area of a sphere = 4πr2, where 'r' is the radius of the sphere.
Solved Examples on Surface Area of a Sphere Calculator
Example 1:
Find the surface area of a sphere if the radius is 5 units?
Solution:
The surface area of a sphere = 4πr2
= 4 × 3.14 × 52
= 4 × 3.14 × 25
= 314 square units
Therefore, the surface area of the sphere = 314 square units
Example 2:
Find the surface area of a sphere if the radius is 7 units?
Solution:
The surface area of a sphere = 4πr2
= 4 × 3.14 × 72
= 4 × 3.14 × 49
= 615.44 square units
Therefore, the surface area of the sphere = 615.44 square units
Example 3:
Find the surface area of a sphere if the radius is 4 units?
Solution:
The surface area of a sphere = 4πr2
= 4 × 3.14 × 42
= 4 × 3.14 × 16
= 200.96 square units
Therefore, the surface area of the sphere = 200.96 square units
Similarly, you can try the surface area of a sphere calculator to find the surface area of the sphere if the radius is
