i don't understand what you trying to say
Area of rectangle = Length*Width
Area of rectangle = 13*9
Area of rectangle = 117
------------------------
The area of a circle formula is
A = pi*r^2
where A is the area of the circle and r is the radius
If the area of the rectangle is equal to the area of the circle, then we can replace the "A" with 117 and solve for r. We'll use 3.14 in place of "pi"
A = pi*r^2
117 = pi*r^2
117 = 3.14*r^2
3.14*r^2 = 117
r^2 = 117/3.14
r^2 = 37.2611464968152
r = sqrt(37.2611464968152)
r = 6.1041908961643
Double this radius to get the diameter
d = 2*r
d = 2*6.1041908961643
d = 12.2083817923286
d = 12.2

just use any point you can find in the graph
and use the dollar to divided by the cups.
the point I chose is 1 dollar for 2 cups. So it's 0.5 dollar for 1cup
Answer:
Step-by-step explanation:
Let x be the random variable representing the number of miles that each person walked each day for 6 months. Since it is normally distributed and the population mean and population standard deviation are known, we would apply the formula,
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = standard deviation
For Rueben,
µ = 5
σ = 1.1
the probability that Rueben walked more than 6.1 miles is expressed as
P(x > 6.1) = 1 - P( x ≤ 6.1)
For x = 6.1,
z = (4 - 6.1)/1.1 = - 1.91
Looking at the normal distribution table, the probability corresponding to the z score is 0.02807
P(x > 6.1) = 1 - 0.02807 = 0.97193
P(x > 6.1) = 0.97 × 100 = 97%
For Victor,
µ = 4.4
σ = 1.4
the probability that Victor walked less than 5.8 miless is expressed as
P(x < 5.8)
For x = 5.8,
z = (5.8 - 4.4)/1.4 = 1
Looking at the normal distribution table, the probability corresponding to the z score is 0.8413
P(x < 5.8) = 0.84 = 84%
