Answer:
11 : 38
Step-by-step explanation:
Because the actual dimensions of the board and the target are missing, let us supply the missing values.
Let:
radius of board = 6 inches
radius of target = 2 inches
Area of board = pi * r^2 = pi*6^2 = 36pi
Area of target = pi * r^2 = pi*2^2 = 4pi
Probability of hitting the target = 4pi / 36pi = 1/9
Therefore, there is a 1/9 chance of hitting the target on the board.
115.5 ft
cut the shape into a square and triangle.
square: 9 x 11= 99
triangle: (6x11)/4 =16.5
99+16.5=115.5
