# Surface Area of a Sphere Calculator

Undoubtedly, a **sphere** is one of the simplest figures in **geometrical** Mathematics. But it can be difficult to **solve** this figure sometimes when you have **complex** values or don’t know **how** to perform a calculation. The main **reason** behind such events is that you may not know the **formula** to perform a calculation or don’t have **enough** skills to do so.

If you are not **familiar** with the calculation of the surface area method of a **sphere**, you should use this online maths calculator. This **surface area of a sphere calculator** has been programmed for **performing** this calculation only. You can **easily** find the surface area using the measurement of the **radius** of that sphere. **Simply**, insert the measure of **radius** and it will display the surface area of that sphere.

## What is the surface area?

t is the **region/area** that is bounded by the boundaries of any **closed** figure, shape, or object. In simple **words**, if you place an object on the **table**, the region that is covered by its boundaries in all directions will be called it's **surface area**.

**For example**, if you have a **cube** that you place on the **table**, it will cover some **region** in all three dimensions. That **particular** region will be called it's surface area as it **covers** the space and region by its **boundaries**.

### What is the surface area of the sphere?

Before you **learn** about the surface area of a **sphere**, you should need to know what this **figure** is. A sphere is a **3D** hollow round shape like a **circle** that is equidistant in all dimensions from a **fixed point**.

In simple **words**, all points on the **boundary **of a sphere will be equidistant from a **fixed** point that we call its **center**. Like a circle, it has a specific **center**, radius, and other related measures. The surface area of a **sphere** is the region that it covers **under** its boundaries.

We can cut it **down** into two equal **parts** from its central **axis** that we call a **hemisphere** which means similar to a sphere. In practical **life**, many professional as well as daily **routine** problems can be **solved** using this specific figure and its surface area calculation. A Sphere is **one** of those shapes in geometry that **cover** the maximum area under its boundaries.

### What is the area of a sphere formula?

Like all other **geometrical figures**, a sphere also has particular **formulas** using which you can find the related measurements. **For example**, you can find the surface area of a sphere **easily** using a specific formula. Here is the formula that you can **use** for this calculation.

Surface area of a sphere = 4𝝿r^{2}square units

Here, “r” represents the radius of the sphere while “𝝿” is a specific constant that has a fixed value i.e. 3.14.

### How to find the surface area of a sphere?

Finding the **surface** area of a sphere isn’t a **difficult** task if you have simple values. You only have to **add** those given measurements in the above **formula** and perform the **concerned** calculation. Still confused? Don’t worry we have **shared** an example here for better understanding.

**Example 1:**

Find the surface area of a sphere if the measure of its radius is 7m.

**Solution:**

As we know,

The surface area of a sphere = 4𝝿r^{2} sq. unit

So,

= 4 (3.14) (7)^{2}sq. m

= 201.06 sq. meter

### How to use the surface area of a sphere calculator?

In case you have a **complex** or **decimal** value of the **radius**, you may not be able to find the surface area of a **sphere** through a manual approach. But you can make the process **simpler** and more accurate using this tool by Calculator’s Bag. Here are the simple steps that you have to follow in this regard,

- Insert the measure or radius in the input box.
- This calculator will automatically display the value of the surface area of a sphere.

### FAQ | Surface Area of a Sphere Calculator

**Why is the area of a sphere 4πr(square)?**

Studies have shown that the surface area of a sphere is 4 times the surface area of a circle with the same radius measurement. That’s why it is calculated using 4πr(square).

**What are the surface area and volume of the sphere?**

The surface area and volume of a sphere are given by,

Surface area = 4𝝿r^{2}

Volume = 4/3𝝿r^{3}

**Why is the volume of a sphere 4/3?**

The entire sphere can be divided into four equal parts vertically and horizontally at the central axis. As the volume involves 3 dimensions, that’s why the volume of the sphere is calculated in 4/3.

**How do you find the volume and surface area of a sphere of radius A? **

If the radius of a sphere is A, then its surface area and volume can be calculated using through following formulas,

Surface area = 4𝝿A^{2}

Volume = 4/3𝝿A^{3}

**What is the surface area of a sphere calculator? **

The surface area of a sphere calculator is an online tool that has been programmed to calculate this measurement quickly, easily, and with accuracy.

**What is the difference between the surface area and volume of a sphere? **

The surface area of a sphere is the measure that belongs to 2 dimensions while the volume belongs to 3 dimensions.
