Answer 1

14π or 43.98 cm

Explanation:

The circumference of a circle is given by the formula:

C = 2πr

where C is the circumference, r is the radius, and π (pi) is a mathematical constant approximately equal to 3.14159.

If the radius of the circle is 7, then the circumference is:

C = 2π(7) = 14π

Therefore, the circumference of the circle with a radius of 7 is 14π. Note that since π is an irrational number, the exact value of the circumference cannot be expressed as a finite decimal, but rather it is typically left in terms of π.
