The area occupied by the sphere’s surface is known as its surface area. When seen as three-dimensional structures, circular forms are most likely to appear as a sphere. A globe or a soccer ball, for example. You will learn how to calculate the surface area of a spherical in this course. Because a sphere is three-dimensional, you’ll learn how to compute its surface area of a sphere.

What is a sphere’s surface area?

The area covered by the sphere’s outer surface is referred to as the sphere’s surface area. A sphere is a three-dimensional solid object having a circular structure, similar to a circle. A sphere is different from a circle in that it is three-dimensional rather than two-dimensional. The surface area of a sphere is the total area of the faces that surround it. The volume of sphere is measured in square units.

The Surface Area of a Sphere is Calculated

Archimedes discovered that if the radius of a cylinder and a sphere are both “r,” the sphere’s surface area equals the cylinder’s lateral surface area. As a result, the relationship between a sphere’s surface area and a cylinder’s lateral surface area is:

Sphere Surface Area = Lateral Surface Area of Cylinder Sphere Surface Area = 2rh

In this scenario, cylinder height Equals sphere diameter = 2r.

As a result, the sphere’s surface area is 2rh = 2r(2r) = 4r2 square units.

Surface Area of a Sphere Formula

If the radius of the produced sphere is r and the sphere’s surface area is S. The sphere’s surface area is then calculated as follows:

S = 4r2 is the sphere’s surface area.

The surface area of a sphere is calculated using the formula S = 4(d/2)2, where d is the sphere’s diameter.

What is the formula for calculating the surface area of a sphere?

The space occupied inside a sphere is known as the surface area of a sphere. The formula for the surface area of the sphere may be used to determine the sphere’s surface area. The following are the processes to calculating a sphere’s surface area:

Step 1: Determine the sphere’s radius.

Step 2: Multiply the radius by itself to get the square of the radius.

Step 3: Divide r2 by four.

Step 4: Multiply the value of 4r2 by 3.14, which is the approximate value of pi.

Step 5: Finally, add the units to the total.

Let’s look at an example to see how to use the formula to determine the surface area of a sphere.

A sphere appears to have a three-dimensional structure that is formed by spinning a circular disc with one of the diagonals. Consider the case of spherical ball faces that are painted. To paint the entire surface, you’ll need to know how much paint you’ll need ahead of time. As a result, the area of each face must be determined in order to calculate the paint quantity needed to paint it. The overall surface area is how we define this phrase.

What is the sphere’s surface area?

The total area covered by a sphere’s outer surface in three-dimensional space is called its surface area.

What is the hemisphere’s surface area?

The sum of a hemisphere’s curved surface area and base area is its surface area.

Conclusion

This was all about the concept of surface area of the sphere. All you need to do is to practice it on different applications and you will be able to enjoy it perfectly. If you still feel that you need help then it is a good idea to enroll yourself in the course from Cuemath. The math experts can help you out in proper understanding.
