just a plain vanilla substitution
<h3><u>Radius as function of volume is:</u></h3>
<em><u>Solution:</u></em>
<em><u>The volume of cone is given as</u></em>:
Where,
r is the radius
h is the height
From given,
height = 20 inches
From formula,
Rearrange , so that r is alone in left side of equation
Substitute h = 20
Thus, radius as function of volume is:
At Gino's you pay $16 plus $8 per pizza.
At Venetian's you pay $24 plus $6 per pizza.
Let the number of pizzas be x.
At Gino's you pay 16 + 8x
At Venetian's you pay 24 + 6x
Set the two costs equal and solve for x to find out the number of pizzas for which both costs are the same.
16 + 8x = 24 + 6x
16 + 2x = 24
2x = 8
x = 4
Each place gives you a free pizza.
4 pizzas plus the free pizza equals 5 pizzas.
If you need 5 pizzas (including the free one), both parlors cost the same.
If you need fewer than 5 pizzas, use Gino's.
If you need more than 5 pizzas, use Venetian's.
