To find the circumference and the area of a circle, we use the formulas:

Circumference = 2πr
Area = πr²

Given that the radius (r) is 8cm and π is approximately 3.14, we can substitute these values into the formulas.

For the circumference:
Circumference = 2 * 3.14 * 8 = 50.24 cm

For the area:
Area = 3.14 * 8² = 3.14 * 64 = 200.96 cm²

So, the circumference of the circle is 50.24 cm and the area of the circle is 200.96 cm².
