Answer:
81pi mm^2
Step-by-step explanation:
The radius is 1/2 the diameter, and is used in finding the area of a circle.
The formula for this is
A = pi(r)^2
So the formula you would use is
A = pi (9)^2
= 81pi
Usually teachers accept it in terms of pi, but if not, you can use 3.14 and multiple it.
I hope this helped!
Answer: 54.29%
Step-by-step explanation:
Given: The probability that they will win both games is 38%.
i.e. P( both games will win) =0.38
The probability that they will win just the first game is 70%.
P(first game will win) = 0.70
To find : P(second game will win| first game will win)
Using formula: 
So, P(second game will win| first game will win) = 

Hence, the required probability = 54.29%
F(x) = -2.5x + 135...where x is the number of weeks, and f(x) = total weight
