What the volume of a sphere with a diameter of 21.4 dm?

Anna007 [38]

Answer:

V ≈ 4577.204 cm^3

Explanation:

Use the volume formula V=4/3πr^3 to find the volume. Since you need the radius but are given the diameter, divide it by 2 to get half.

21.4/2 = 10.7

Now plug that into the formula and solve:

V=4/3πr^3

V=4/3π(10.7)^3

V= 4/3π(1,092.7272)

V= 4/3 * 3432.903

V= 4 * 3432.903/3

V = 13731.614/ 3

V ≈ 4577.204 cm^3 or whatever unit is stated.

Dovator [93]

Answer:

Masks can tell the stories that have been passed down for generations. They can represent enemies by having bigger and scarier looking masks, while smaller and more pleasant looking ones can represent the good characters. Colors can play a part in what the masks may represent. For example, red could mean evil and blue can mean sadness. Animals and fantasy characters may also be represented through these masks.

Why is eliminating child labor problematic?

DaniilM [7]

Eliminating child labor is problematic (in third world countries) because of outsourcing. We have our products made in foreign countries with no child labor laws because it's cheaper. We eliminate child labor, the price of production goes up and bushiness have to charge more to cover the costs, hiking the prices to consumers in our economy. Therefore, big companies don't really want child labor to be eliminated. A lot more could be done about it, but many people choose not to help for their own personal gain.
