Answer: $1.50/cookie
Step-by-step explanation:
Cookies = x
Water = y
5x + y = $8.75
y = 1.25
Plug in y-value into equation:
5x +1.25 = 8.75
5x = 8.75 - 1.25
5x = 7.50
x = 7.50/5
x = $1.50 for 1 cookie.

The formula for the height of a cylinder is h = V / (π.r²) and the height of a cylinder with a volume of 36 cm³ and a radius of 3 cm is 4/π cm
Given a cylinder with a radius r and height h, then its volume is given by the formula:
V = π.r².h
Where:
V = volume
r = radius
h = height
To find the formula for the height, divide both sides by π.r²
V : π.r² = π.r².h : π.r²
or,
h = V / (π.r²)
The given parameters are:
V = 36 cm³
r = 3 cm
Substitute those parameters into the formula:
h = 36 / (π.3²)
h = 36 / (9π)
h = 4/π cm

Answer:
Step-by-step explanation:
we know that
The diameter of the largest possible circle is equal to the length side of the square
The approximate area of the remaining board is equal to the area of the square minus the area of the circle
so
we have
------> length side of the square
-----> the radius is half the diameter
substitute the values
Round to the nearest whole number
