Exact Answer: 12pi

Approximate Answer: 37.68

The approximate answer is when you use the approximation pi = 3.14

==============================================================

Step-by-step explanation:

The area of the full circle is

A = pi*r^2

A = pi*4^2

A = 16pi

Take 3/4 of this to get the area of the "pacman" like shape that is shown

(3/4)*16pi = (3/4*16)pi = 12pi

12pi = 12*3.14 = 37.68 approximately
