The volume of a cylinder is V=pi*r^2*h

We just have to plug in:
V=pi*25*8 (now plug into the calculator)
V=628.3 cubic cm

As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second. Convert this speed to kilometers

Ira Lisetskai [31]

Answer:

The kilometers Jupiter travel in 5 seconds is 64 kilometers.

Step-by-step explanation:

Given:

As Jupiter revolves around the sun, it travels at a speed of approximately 8 miles per second.

1 mile is equal to 1.6 kilometers.

Now, to convert this speed to kilometers per second, and at this speed to find kilometers will Jupiter travel in 5 seconds.

So, to convert speed of miles per second into kilometres per second:

1 mile = 1.6 kilometres.

Thus, 8 miles = 8 × 1.6 = 12.8 kilometres per second.

Now, at this speed we calculate the kilometres Jupiter travel in 5 seconds by multiplying:

In 1 second Jupiter travel = 12.8 kilometres.

So, in 5 seconds Jupiter travel $=12.8\times 5$

$=64\ kilometers.$

Therefore, the kilometers Jupiter travel in 5 seconds is 64 kilometers.

If x is increased by 25% then, by what % is x² increased

Alinara [238K]

By analytical methods and algebraic handling and on the basis that x is increased by 25 %, we conclude that the variable x² is increased by 18.75 %.

<h3>How to determine the percentage increase rate </h3>

In this case we have a linear variable x, whose increase is described by the following expression:

y = x · (1 + r/100) (1)

Where r is the increase rate.

If we square (1), then we find that:

y² = x² · (1 + r/100)² = (1 + r'/100) (2)

Where r' is the equivalent increase rate.

(1 + r/50 + r²/10000) = (1 + r'/100)

r'/100 = r/50 + r²/10000

r' = r/2 + r²/100

If we know that r = 25, then the equivalent increase rate is:

r' = 25/2 + 25²/100

r' = 18.75

By analytical methods and algebraic handling and on the basis that x is increased by 25 %, we conclude that the variable x² is increased by 18.75 %.
