# What is the circumference of 16 cm circle?

## What is the circumference of 16 cm circle?

50.27 in

16π≈50.27 in.

### How do you find the circumference of 16 cm?

The circumference of a circle is equal to Pi π times the diameter d . Since the diameter d is equal to 2 times the radius r , the formula for circumference using radius is 2πr 2 π r .

**What is the diameter of a 16 cm circle?**

8 centimeters

162=8 centimeters.

**How do you convert cm to circumference?**

Let’s assume it’s equal to 14 cm. Substitute this value to the formula for circumference: C = 2 * π * R = 2 * π * 14 = 87.9646 cm . You can also use it to find the area of a circle: A = π * R² = π * 14² = 615.752 cm² .

## What is the radius of 16 cm?

8 cm

If the 16 cm is the diameter then the radius is 8 cm.

### How do you find the area of a 16cm circle?

Pre-Algebra Examples

- The area of a circle is equal to Pi π times the radius r squared. π⋅(radius)2.
- Substitute in the value of the radius r=16 into the formula for the area of a circle. Pi π is approximately equal to 3.14 . π⋅162.
- Raise 16 to the power of 2 . π⋅256.
- Move 256 to the left of π . 256π(cm)2.

**What is the area of a 16 cm square?**

Area of given square = a * a = 4 cm * 4 cm = 16 cm^2. Now, m^2 = cm^2 / 100^2. Hence Area of given square in m^2 = 16 / 10000 = 0.0016 m^2. Originally Answered: The perimeter of a square is 16cm.

**How do you find a circumference?**

To find the circumference of a circle, multiply the circle’s diameter by pi (3.14).

## How do you find the circumference of 12 centimeters?

So, if d=12 cm, r=12(12)=122=6 cm.

### What is a circle diameter?

The diameter is the length of the line through the center that touches two points on the edge of the circle.

**How do you find the diameter if you have the circumference?**

How to find the circumference of a circle: The circumference of a circle can be found by multiplying pi ( π = 3.14 ) by the diameter of the circle. If a circle has a diameter of 4, its circumference is 3.14*4=12.56. If you know the radius, the diameter is twice as large.

**What is the area of a circle with a diameter of 16 in?**

Formula for area of a circle is pi*radius^2. The radius of a circle is half the diameter. Since the diameter given is 16 inches, the radius is 8 inches.

## What is circumference vs. diameter?

• Radius and diameter are straight lines while circumference is a closed curve. • Diameter is twice as the radius. • Circumference is 2π times the radius of the circle or π times the diameter of the circle.

### What is the circumference of 16?

A circle of radius = 8 or diameter = 16 or circumference = 50.27 cm has an area of: 2.011 × 10 -8 square kilometers (km²) 0.02011 square meters (m²) 201.1 square centimeters (cm²)
