Answer:
Yes, r and h can be changed to produce same volume by;
Increasing "r" and decreasing "h" or by decreasing "r" and increasing "h".
Step-by-step explanation:
What the question is simply asking is if we can get same volume of a particular cylinder if we change the radius and height.
Now, volume of a cylinder is;
V = πr²h
Now, for the volume to remain the same, if we increase "r", it means we have to decrease "h", likewise, if we decrease "r", we now have to increase "h".
Answer:
x + 6
Step-by-step explanation:
consider the x- coordinates of the right angle
x- coordinate of A = - 4
x- coordinate of B = 2
then
| 2 - (- 4) | = | 2 + 4 | = | 6 | = 6
the x- coordinate has been shifted 6 units to the right , so the rule is
x + 6
The length of AD is 5 units. so, option A is the correct answer.
<h3>What is the Pythagoras theorem?</h3>
The Pythagoras theorem states that the square of the longest side must be equal to the sum of the square of the other two sides in a right-angle triangle.
The length of DC is given as 13 units.
The length of AC is given as 12 units. We can see that angle D is a right angle, so the triangle will be a right-angle triangle.
by Pythagoras theorem;
![DC ^2 = AD^2 + AC^2\\\\13^2 = AD^2 + 12^2\\\\AD^2 = 169 - 144\\\\AD^2 = 25\\\\AD = 5](https://tex.z-dn.net/?f=DC%20%5E2%20%3D%20AD%5E2%20%2B%20AC%5E2%5C%5C%5C%5C13%5E2%20%3D%20AD%5E2%20%2B%2012%5E2%5C%5C%5C%5CAD%5E2%20%3D%20169%20-%20144%5C%5C%5C%5CAD%5E2%20%3D%2025%5C%5C%5C%5CAD%20%3D%205)
Hence, the length of AD is 5 units. so, option A is the correct answer.
