What is the surface area of the cube below? 9 9 9

Mathematics
1 answer:
Natali5045456 [20]3 years ago
3 0

Answer:

A_s=486\ units^2

Step-by-step explanation:

Remember that the sides of a cube always have the same length.

In this case the length of the sides L is:

L = 9.

The cubes have 6 faces. Then the surface area of the cube is equal to the area of its 6 faces.

Since all sides of the cube have the same measure, then the area of each face is:

A = L ^ 2

Then the area of the 6 faces is:

A_s = 6L ^ 2

A_s = 6 * (9 ^ 2)

A_s=486\ units^2

Auto insurance Insurance companies collect annual pay-ments from drivers in exchange for paying for the cost of accidents.a) Why
Igoryamba

Answer:

Step-by-step explanation:

a) Because you are only receiving $1500 and in exchange you would have to cover for this accident damage in the next year, which could be up to hundred of thousands of dollar. Sure there's a chance the your neighbor might drive safely, but the odds are far more in his favor than yours.

b) The insurance company collect payments from hundred of thousands buyers, making their cash flow up to tens of million dollar. Sure the expected value of accidents might be high but as a company they surely have capital to cover a handful of cases, if their calculation done right.

Burka [1]

First, by using the distance formula for just one side, we can find the length of all sides (a square has 4 equal sides.) Then, we can apply the area of a square formula, which is a^2.

Distance formula:

\sqrt{(x.2 - x.1)^{2} + (y.2 - y.1)^{2}}

√((-2 + 5)^2 + (-8 + 4)^2)

√((3)^2 + (4)^2)

√9 + 16

√25

5

The side lengths of the square are each equal to 5, and by applying the formula for area, we can find the area of the square.

5^2 = 25

<h3>The area is 25.</h3>
