Question

the diameter of circular metalic sheet is 2:3 found out it's circumference and are​

Answer 1

Answer:

We know that the the distance from the center point to any point on the circumference of a circle is a fixed distance, known as the Radius of a circle.

Therefore, the relation between Radius and Diameter is

Diameter=2×Radius

Step-by-step explanation:

Circumference:

We know

Circumference = 2πr

It can be re-written as, (2r)×π

= d×π

 

Area:

We know

Area=  πr2

It can be re-written as π(2r)24

=π4.d2
