Seagull

An artificially created island in the shape of a circle with a radius of 50 m is overgrown with grass. The only exception is a landing area for helicopters in the shape of a rectangle measuring 15 m and 8 m. What is the probability that the flying seagull (without the use of the senses, eyes, ......) makes land at the landing area?

Correct answer:

p =  1.5279 %

Step-by-step explanation:

$$\begin{gathered} S_1=\pi \cdot 50^2=3.1416\cdot 50^2\doteq 7853.9816 \\ {S}_2=15\cdot 8=120 \\ p=100\cdot S_2/S_1=100\cdot 120/7853.9816=1.5279\% \end{gathered}$$
