October 19, 2023 written by Rida Mirza

Circumference is a fundamental concept in geometry. It representing the distance around the edge of a circle. It plays an important role in various mathematical and real-world applications.

In this article, we will discuss ten examples of circumference in mathematics.

## Examples of Circumference

These are 10 examples of circumference.

### 1: Calculating Circumference from Diameter

Given a circle with a diameter of 10 cm. Find its Circumference.

We calculate the circumference using the formula,

C = πd

Substituting the values,

C = π * 10 = 31.42 cm

### 2: Calculating Circumference from Radius

If the radius of a circle is 6 cm. Find its circumference.

We find the circumference using the formula,

C = 2πr

Plugging in the values,

C = 2 * π * 6 = 37.70 cm

### 3: Finding the Circumference of a Tire

Suppose you have a car tire with a radius of 15 inches. Find its circumference.

The circumference calculate using,

C = 2πr

C = 2 * π * 15 = 94.25 inches

### 4: Determining the Circumference of a Pizza

Given a pizza with a diameter of 18 inches. Find its circumference.

We find its circumference by applying,

C = πd

Thus,

C = π * 18 = 56.55 inches

### 5: Circumference of a Running Track

Imagine a circular running track with a radius of 100 meters. Find circumference.

The circumference calculated by using,

C = 2πr

C = 2 * π * 100 = 628.32 meters

### 6: Circumference of a Hula Hoop

For a hula hoop with a radius of 30 inches, find the circumference of hoop.

We use this formula to find circumference,

C = 2πr

C = 2 * π * 30 = 188.50 inches

### 7: Circumference of a Circular Garden

Suppose you have a circular garden with a radius of 8 feet. Find its circumference.

To find the circumference apply,

C = 2πr

C = 2 * π * 8 = 50.27 feet

### 8: Circumference of a Bicycle Wheel

A bicycle wheel has a diameter of 26 inches. Find the circumference of wheel.

To calculate its circumference,

C = πd

C = π * 26 = 81.68 inches

### 9: Circumference of a Circular Pool

A circular swimming pool has a diameter of 30 meters. Find its circumference.

Circumference calculate by using,

C = πd

C = π * 30 = 94.25 meters

### 10: Circumference of a Pie Crust

When making a circular pie crust with a radius of 9 inches. What is circumference of pie.

To find Circumference use this formula,

C = 2πr

C = 2 * π * 9 = 56.55 inches
