The tennis ball's distance from the eye can be determined by using similar triangles.

The distance of the tennis ball from the eye to block out the Sun is; 24.3 feet.

Reasons:

The given parameter are;

The ratio of the shadow to the objects diameter = 108 : 1

[tex]\dfrac{108}{1} = \dfrac{Distance \ of \ tennis \ ball}{2.7}[/tex]

The distance of the tennis ball from the eye = 108 × 2.7 in. = 291.6 in.

291.6 inches = 24.3 feet

The distance of the tennis ball from the eye to block out the Sun is 24.3 feet.
