Answer 1

hey mate your answer is here

given = a circle with radius 4cm

what is the circumference of circle???

so it is 2πr square

now,

= 2x22/7x4

= 25.14 CM is the circumference

Answer 2

Concept:

The circumference of a circle or ellipse is its perimeter. That is, if the circle was expanded up and straightened out to a line segment, the circumference would be the arc length of the circle.

Given:

Radius of the circle = 4cm

To find:

The circumference of the circle.

Solution:

The circumference of a circle or ellipse is its perimeter. That is, if the circle was expanded up and straightened out to a line segment, the circumference would be the arc length of the circle.

Circumference of the circle= $2\pi r$

=2×3.14×4

=25 .12

=circumference of the above circle is 25.12 sq. cm
