Question

:. A circular area is marked on a rectangular
patch as a target for a certain game. A
player is declared winner if a ball thrown
lands in the circular area. Then what is
the winning probability for a participant
given that the dimension of rectangle are
2 m and 3 m while the radius of circle is
0.5 m ?


​

Answer 1

Answer:Area of the circle = πr  

2  =  4 π(1)  

2  =  4 π  sq m.

Area of the rectangle =3×2=6 sq m.

P(Die will land in the circle)=  

Area of rectangle

Area of circle  =  24π

​ P(Die will land in the circle)=  24π

​

Answer 2

dimensions of rectangle =2m,3m

area of rectangle=2×3=6

radius of circle=0•5m

area of circle=π×r×r

=55/70

P(landing a ball in circular area)=55/70×1/6

=11/84
