That 10 is the diameter of the circle. First let's find the area of the square. A = s^2 Where 's' is the side. A = 10^2 A = 100 Now let's find the area of the circle. The '10' is also the diameter of the circle. A = pi * r^2 A = 3.14 * 5^2 A = 3.14 * 25 A = 78.5 Now subtract this from the area of the square. 100 - 78.5 = 21.5 So the approximate area of the shaded region is 21.5cm^2
i did it 3 times just now. i got. 2 heads, 1 tail. i keept on doing it but i keep on getting 2 heads and 1 tail. but once i got 1 head and 2 tails. but most likely you will get 2 head and 1 tail.
