How do you change the height of a square pyramid so that its volume would remain the same when the area of the base is tripled?
It must be made a third of its current value, ie divided by 3. The volume of a pyramid is 1/3 x area_base x height. The 1/3 is constant; to keep the volume constant as the base_area changes, the height must vary inversely. If the base_area is tripled, ie multiplied by 3, the height must be reduced to a third, ie divided by 3.
What happens to the volume of the rectangular prism in number 1 if the length is tripled?
I'd need to review what happened in number-1 before I could answer that. I do know that if only the length of a rectanguar prism is tripled, while the other two dimensions remain unchanged, then its volume triples.
What happens to the area of a circle if yo double the radius?
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
How do you calculate the coordinates of chord given the length of radius and chord?
You cannot. If you rotate the circle around its centre, the lengths of the radius and chord will remain the same but the coordinates of the chord will change.
Why the focal length of concave mirror changes in water?
I don't think so. The focal length would remain the same. It mainly depends on the radius of curvature of the mirror.

Would the height of a tree be greater in feet or inches?
The height would remain the same.
What are remain of organisms that are actually changed to rocks are called?
Fossils.

You cannot. If you rotate the circle around its centre, the lengths of the radius and chord will remain the same but the coordinates of the chord will change.
Remain of organisms are actually changed to rock are called?
the answer is petrified fossils
What will happen to youngs modulus of steel if radius is doubled?
young modulus remain unaffected ...as it depends on change in length ..
If a custody case is reopened does current order remain in effect?
Until changed.
When a rock is placed in a graduated cylinder containing water the height of the water will what?
remain the same
When a triangle is enlarged by a factor 3 are the angles tripled in size?
No - if the lengths of the sides are all increased by a factor of 3, the angles remain unchanged. You just wind up with a "similar" triangle 3 times the size of the original. A quick counterexample would be to consider what would happen if the angles DID change. The sum of the angles in the original triangle should be 180°. If the angles in the new, larger triangle tripled in size, the sum of the angles in the bigger triangle would be 540° - but the sum of the angles of a triangle should always remain 180°.
What happened to the melody when you changed the tempo?
When the tempo is changed, the melody may sound faster or slower, but the notes and structure of the melody remain the same.
