Answer:
By knowing the formulas for the volume of the solids.
Step-by-step explanation:
To find it out, you need to know the formula for the solids shown such as the cone and the cylinder. The formula for the cone is 1/3hπr². The formula for the cylinder is hπr².
If you were asking for the answers,
Cone:
The radius for the cone is 12 inches.
Cylinder:
The height for the cylinder is 3.8 inches.
Well, if you cut a circle in 4 parts, each part will equal 90 degrees. But if you cut one of those parts in half again it will cut the degrees in half. Thus, making the degrees of that half a part 45. Your answer should be 45 degrees.

Destiny has 4*.49 = 1.96 L of acid. In order for the 1.96 L of acid to be 14% of the solution, there must be 1.96/.14 = 14 L of solution.
Destiny must add 14 L -4 L = 10 L of water to make the desired solution.
