To find:
The volume of the water in the cup when it is full.
Solution:
The volume of the water is equal to the difference of the volume of the small cone and the larger cone.
Here, the ratio of the radius of both cones is equal to the ratio of their heights. SO,
The radius of the larger cone is 4.5 cm.
So, the volume of the water is:
The volume of water when the cup is full is 332.64 cm^2.
For this case we have that the original price of the book is given by:
$ 19.75
The customer has a coupon to save part of the price of the book.
Therefore, the customer will pay
Where,
x: value of the customer coupon.
We know that the customer has a coupon that has a value of $ 4.50.
Substituting values we have:
