The **Moeraki Boulders** are stone spheres along the coast of New Zealand. A formula for the radius of a sphere is $ r = \frac{1}{2} \sqrt{\frac{S}{\pi}} $, where $ S $ is the surface area of the sphere. Find the surface area of a Moeraki Boulder with a radius of 3 feet.

### 52. Drawing Conclusions

**"Hang time"** is the time you are suspended in the air during a jump. Your hang time $ t $ (in seconds) is given by the function $ t = 0.5h $, where $ h $ is the height (in feet) of the jump. Suppose a wallaby and a skier jump with the hang times shown.

### Image Details

#### Graph
At the top of the image, there is a graph displaying the function $ y = 2 \sqrt{x} - 4 $. The graph is plotted on a standard Cartesian plane with the x-axis representing the independent variable $ x $ and the y-axis representing the dependent variable $ y $. The plot of the function shows an upward curve starting from the point (4,0), reflecting the square root function transformed by a vertical stretch and a vertical downward shift.

### Visuals
The image includes a photo of a wallaby in the lower left and a skier in the lower right, indicating their different jump heights and hang times mentioned in problem 52.
