Answer:
4.123 units
Step-by-step explanation:
Data provided:
Coordinates of point 1 as ( 4 , 2)
and,
Coordinates of point 2 as ( 0 , 1 )
Now,
The distance between the two point whose coordinates are given is calculated using the formula as:
distance = 
on substituting the values, we get
distance = 
or
distance = 
or
distance = 
or
Distance = √17 = 4.123 units
S = 4pi r^2
S/4pi = r^2
taking square root on both sides,
r = sqrt (S/4pi)
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.
Did you say he can choose " 1 snack " ?
Well then. There are 9 different items in the box, so he has
9 different choices of snack.
I guess that means he can choose his snack in 9 ways.
