Volume and surface area of a solid hemisphere are numerically equal. what is the diameter of hemisphere?

The diameter of hemisphere is 9

Step-by-step explanation:

∵ the volume of the sphere is

∴ The volume of the hemisphere is

∵ The surface area of the hemisphere is

∴ The surface area of the hemisphere

∵ The volume of the hemisphere = the surface area of it

∴ ⇒divide both sides by πr²

∴

∴ r =9/2

∴ The diameter of the hemisphere is 9

18.8 cubic inches.

step-by-step explanation:

volume of a cone = πr²h

r = 1.5 inches

h = 8 inches

pi = 3.14

volume of our cone = × 3.14 × 1.5² × 8 = 18.84 square inches

or equals to 18.8 square inches rounded up to nearest tenth.

the central idea is that:

individuals should refuse to cooperate with institutions they believe unjust.

thoreau felt  that governments were more often agents of corruption than justice, even democracies, and that just because the majority feels a certain way does not make it just or correct in absolute terms. he uses the fact that slavery exists in our democracy to support this idea.

he goes on to say that, as a result, people should live true to their own internal laws regarding right and wrong, as a product of reflection and a moral life, rather than following every law that society imposes.
