Question

take any two circluar object and find it circomefarence and also find(pi)​

Answer 1

Step-by-step explanation:

What is the circumference of a circle?

The perimeter of a circle is known as its circumference.

• Trace the outline of a few circular objects of different sizes like a CD, a circular bottle lid, a frisbee, a round bowl and a key ring on paper and cut them along their circumference. Then, do the following:
• Measure the diameter of each circle by folding in half.
• Measure the circumference of each circle using a string.
• Record both readings in a table as below.

As you will notice, the circumference of each object is about 3 times its diameter.

More precisely, the circumference of a circle is 22/ 7 times its diameter.

The value 22/ 7 is represented by π and read as pi.

The approximate value of π is 3.14.

What is the formula to calculate circumference of a circle?

Circumference = π × Diameter

Or,

Circumference = π × 2 × Radius = 2 × π × Radius
