total area =700 sq.km
total area of lake = πr^2
=3.14 ×10×10 =314 km
probability =314/700=157/350

It's very easy , let's solve it


The area of Rectangle Field. = 700 sq km

n( s) = 700

Now the area of the circle inside

= π × r²

= 3.14 × (10)²

= 3.14 × 100

= 314 sq km

n ( A) = 314


The probability of


Now the missing helicopter it has crashed inside a circular lake of radius 10 km well inside the park is

P ( A) = n (A)/ n ( S)

= 314 / 700

= 314 / 700 ÷ 7/7 ..... Dividing by 7 to to get Percentage

44.86 % = Probability

Hope it helps
