Given the circle, state your answers in EXACT and decimal form. 

1. What is the area of the shaded region? 

Exact Form: \( \square ft ^ { 2 } \)  Use \(\pi \) in your answer. 

Approximate Form: \( \square ft ^ { 2 } \) (2 dec. places.) 

The diagram shows a regular polygon. What is the value of \( x \) ? 

Write your answer as an integer or as a decimal rounded to the nearest tenth. 

\( x = \square ° \)
