Answer:
The height of the cone is 
Step-by-step explanation:
we know that
The volume of a cone is equal to
In this problem we have
----> the radius is half the diameter
assume 
substitute the values and solve for h
F(y) = y + y^2 - 3
f(-2) = -2 + (-2^2) - 3
f(-2) = -2 + 4 - 3
f(-2) = -1
f(-4) = -4 + (-4^2) - 3
f(-4) = -4 + 16 - 3
f(-4) = 9
f(0) = 0 + 0^2 - 3
f(0) = -3
f(2) = 2 + 2^2 - 3
f(2) = 2 + 4 - 3
f(2) = 3
f(4) = 4 + 4^2 - 3
f(4) = 4 + 16 - 3
f(4) = 17
To answer this first we will subtract d amount of dollars Boy had by d amount of dollars he had left in d end. den we will divide d amount of dollars he used by d amount of books he bought. den d answer will be d amount of money each book cost. Lets do it:-
$266 - $18 = 248
$248 ÷ 6 books = 41.33333.....
So, 1 book costs about 41.50.
Hope I helped ya!! xD
