Answer 2

Answer:

Given the radius of circle=2cm

Then one side of square=2+2=4cm

Area of circle =πr

$\frac{22}{7} \times {2}^{2} = \frac{22}{7} \times 4 = 12.57 {cm}^{2}$

Area of square

${a}^{2} = {4}^{2} = 16 {cm}^{2}$

Then the area of shaded region=16−12.57=3.43cm ^2

Then % probability of hits in shaded region =

$\frac{3.43}{16} \times 100 = 21.44\%$
