## Square in a Circle Calculator

### How to Use the Calculator

Using the Square in a Circle Calculator is simple. You need to:

- Enter the radius of the circle (r).
- Click on the “Calculate” button.
- The calculator will display the area of the square that fits inside the circle.

**Input Fields:**

- Radius of the circle (r)

**Example Input:**

- Radius (r): 5 units

**What is a Square in a Circle?**

A square in a circle is the The largest square that fits inside a circle has sides equal to the circle’s diameter divided by the square root of 2.

### How to Calculate the Square Inside A Circle

To calculate the area of the square inside a circle, follow these steps:

**Formula:**

`$\text{Area of square} = 2 \times r^2$`

**Variables:**

Variable | Description |
---|---|

r | Radius of the circle |

**Solved Example**

**First Step:**Measure the radius of the circle.**Second Step:**Square the radius.**Third Step:**Multiply the squared radius by 2.**Final Step:**The result is the area of the square.

**Example Calculation:**

If the radius of the circle is 5 units:

First Step:

$r = 5$

Second Step:

$r^2 = 25$

Third Step:

$2 \times r^2 = 2 \times 25 = 50$

Final Step: The area of the square is 50 square units.

### Calculation Example

**Basic Example:**

Input |
Value |
---|---|

Radius (r) | 3 units |

**Calculation:**

$r^2 = 3^2 = 9$

$2 \times 9 = 18$

Area of the square = 18 square units

**Advanced Example:**

Input |
Value |
---|---|

Radius (r) | 7 units |

Calculation:

$r^2 = 7^2 = 49$

$2 \times 49 = 98$

Area of the square = 98 square units

### FAQs

**Q1: Can this calculator be used for any circle size?**

Yes, you can use this calculator for any circle size as long as you know the radius.

**Q2: What if I only have the circle’s diameter?**

If you know the diameter, divide it by 2 to find the radius and then use the calculator.

**Q3: Is the area of the square always less than the area of the circle?**

Yes, the area of the square will always be less than the area of the circle.
