Question

what is the perimeter of the circle

Answer 1

perimeter of a circle = 2πr
it is also called circumference of the circle .

in this formula , π is a constant which is equal to 22/7 or 3.14 . we use 22/7 generally but 3.14 can be used if it is indicated in question

r is radius of circle

2πr can be written as πd , as 2 × radius of circle = diameter of circle .
so , 2r = d

if diameter is given in question , formula πd can be used to take out circumference of circle

hope this helps

Answer 2

Hey dear!!

The perimeter of the circle is known as the circumference of the circle in a better way since a circle is a curved figure.

The formula for finding the circumference of a circle is:

2πr or πd
Where 'r' refers to the radius of the circle and 'd' refers to the diameter of the circle.
