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