# 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

1. The area of a circle is equal to Pi π times the radius r squared. π⋅(radius)2.
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.
3. Raise 16 to the power of 2 . π⋅256.
4. 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)
