Answer:

The correct answer is C) V = pi(3.5)^2h

Step-by-step explanation:

This is because the formula for the volume of a cylinder is pi times the radius squared times the height. We are given a diameter of 7. To get the radius, we must cut that in half to get 3.5. Then we can plug that value into our equation and get the equation above.

The product of two rational numbers is 9⁄7 and one of them is 15⁄14. Then the other rational number is

Rasek [7]

Answer:

The other rational number in the operation given is:

<u>6/5</u>

Step-by-step explanation:

To obtain the number in the operation given, we're gonna represent the operation:

r * 15/14 = 9/7

Where:

r = the other rational number.

Now we are going to solve r to identify its value in numbers:

r * 15/14 = 9/7

$r = \frac{\frac{9}{7} }{\frac{15}{14}}$ (We pass a number that is multiplying to the left of the equal, to divide to the right of the equal symbol)

$r = \frac{6}{5}$

As you can see, when we operate, <u>the result is 6/5</u>, and we can prove this multiplying as we had in the original equation, replacing r by 6/5:

r * 15/14 = 9/7
6/5 * 15/14 = 9/7
9/7 = 9/7

In this form, we know the result is correct.
