Question

Find the circumference of a circle with diameter 100 cm​

Answer 1

Step-by-step explanation:

d=100cm

r=50cm

circumference=2πr

=2*π*50

=100π

Answer 2

Answer:

The circumference is $100$π.

Step-by-step explanation:

It is given that the diameter of circle is $100cm$.

We need to determine the circumference.

Circumference is defined as the boundary of the circle.

It is calculated as product of twice the radius and pi.

OR

It is calculated as product of diameter and pi.

Mathematically,

Circumference $=2r$*π.

Since diameter is given,

Circumference $=d$π

Putting values,

Circumference $=100$π
