Find the circumference of a circle radius =7cm

Answer 1

The formula for the circumference of a circle is:

C = 2πr

where C is the circumference, π is pi (approximately 3.14), and r is the radius.

Substituting r = 7cm, we get:

C = 2π(7) = 14π

So the circumference of the circle with radius 7cm is approximately 43.98cm.
