Question

A circle has a diameter of 4 meters.
What is its perimeter (to the nearest hundredth)?

Answer 1

When the shape is a circle, its perimeter is called the
"circumference" of the circle.

The circumference of a circle is always (pi) times its
diameter.

(pi) is roughly 3.1416 . So if the diameter is 4 meters,
then the circumference is

12.5664... meters .

Rounded to the nearest hundredth, that's 12.57 meters.

Answer 2

Perimeter of circle = 12.57 meter.

Explanation:

Given : A circle has a diameter of 4 meters.

To find : What is its perimeter (to the nearest hundredth).

Solution : We have given that diameter = 4 meters.

Perimeter of circle = pi * diameter.

Perimeter of circle = 3.14 * 4.

Perimeter of circle = 12.566

Perimeter of circle = 12.57 meter.

Therefore, Perimeter of circle = 12.57 meter.
