A container is made up of a hollow cone with an internal base radius of r сm and a hollow cylinder with the same base radius and an internal height of 4r cm. Given that the height of the cone is three-fifths of the height of the cylinder and 7 litres of water are needed to fill the conical part of the container completely, find the amount of water needed to fill the container completely, giving your answer in litres.

walter needs to make at least 5 more cookies but no more than 40. 5 ≤ x ≤ 40

step-by-step explanation:

20 ≤ x + 15 ≤ 55

20-15 ≤ x + 15-15 ≤ 55-15

5 ≤ x ≤ 40

this means how many more cookies he has to make
