To solve the problem, we can use the principle of similar triangles. Both the radio tower and the yardstick form similar triangles with their shadows. This means the ratios of their heights to the lengths of their shadows are equal.

Given:

• Shadow of the radio tower = 8 feet
• Height of the yardstick = 1 yard = 3 feet
• Shadow of the yardstick = 0.5 inches = $\frac{1}{24}$ feet

Let $h$ be the height of the radio tower. We can set up the following proportion:

$\frac{h}{8} = \frac{3}{\frac{1}{24}}$

First, convert $\frac{1}{24}$ feet to a single fraction:

$\frac{3}{\frac{1}{24}} = 3 \times 24 = 72$

So the proportion becomes:

$\frac{h}{8} = 72$

Solving for $h$:

$h = 72 \times 8 = 576 \text{ feet}$

Therefore, the height of the radio tower is 576 feet.
