Answer:
The perimeter of the given rectangle = 20 units.
Step-by-step explanation:
Length of the rectangle = 6 units
The width of the rectangle = 4 units
Now Perimeter of the Rectangle = 2 ( LENGTH + WIDTH)
⇒Here, perimeter = 2 ( 6 units + 4 units ) = 2 x ( 10 units)
= 20 units
Hence, the perimeter of the given rectangle = 20 units.
First you need to find the volume of the cylinder. Then find the volume of all 4 rubber balls (spheres). Subtract the cylinder's volume by the spheres' volumes.
Volume of cylinder: πr²h
π2.5²(20) = 392.7 cm³
Volume of sphere: 4/3πr³
4/3π2.5³ = 65.45 cm³
392.7 - 65.45 = 327.25
The amount of space in the container unoccupied by the rubber balls is 327 cm³.

56 is the answer to the question hi
Answer:
Obtuse
Step-by-step explanation:
The sum of squares of the short sides is 130, so is less than the square of the long side. The long side (12) is longer than it would need to be for a right triangle, so the largest angle is bigger than 90°.
The triangle is obtuse.
_____
A triangle solver app or calculator can confirm this. Note angle C is about 96°, an obtuse angle.
