A circle has a radius of 7 cm. Find its circumference and area in terms of π.

The circumference of a circle is given by:
C = 2πr

Substitute r = 7:
C = 2π(7)
C = 14π

So the circumference is 14π cm.

The area of a circle is given by:
A = πr^2

Substitute r = 7:
A = π(7^2)
A = 49π

Therefore, the circumference is 14π cm and the area is 49π cm².
