Step-by-step explanation:
If a ≤ b ≤ c is the length of the sides, then a + b > c.
(a)
We have a = 3cm, b = 4cm, c = 6cm.
Check:
a + b = 3cm + 4cm = 7cm
c = 6cm
7cm > 6cm → a + b > c CORRECT :)
YES. It's possible.
(b)
We have a = 1cm, b = 3cm, c = 4cm
Check:
a + b = 1cm + 3cm = 4cm
c = 4cm
4cm = 4cm → a + b = c
NO. It's impossible.

Answer:
The radius of hole is 5 feet
Step-by-step explanation:
Depth of conical hole = 9 feet
Let the radius of hole be r
Volume of conical hole =
So, Volume of conical hole =
We are given that volume of a CONE-shaped hole is 75pi ft cubed.
So,
r=5
Hence The radius of hole is 5 feet
When a shape is rotated, it must be rotated around a point.
<em>See attachment for the image of each rotation.</em>
To do this, the top coordinates of the X shape will be transformed using the appropriate rotation rule; the same rule will then be applied to the other parts of the X shape.
The top coordinates of the X shape are:
For 90 degrees counterclockwise rotation, the rule is:
So, we have:
For 180 degrees rotation, the rule is:
So, we have:
For 270 degrees counter rotation, the rule is:
So, we have:
