#### Answer

c = 16$\pi$ cm
A = 64$\pi cm^{2}$

#### Work Step by Step

Given the radius of the circle = 8cm
The circumference of the circle is given by the formula
c= $\pi$ d = 2$\pi$ r
=2$\pi$ * 8 = 16$\pi$ cm
The area A of a circle whose radius has length r is given by
A = $\pi r^{2}$cm
= $\pi 8^{2}$
=64$\pi cm^{2}$
