Why is 2x 3/4 less than 2?
Kipish [7]

Answer & Step-by-step explanation:

It is less because 2 times 3/4 is the same as 2/1 times 3/4 which is 6/4 then simplify it and you get 3/2 which then is 1 1/2.

That is why 2 times 3/4 is less than 2.

Hope that helps ;)

How much water is in the cylinder ?
Mariulka [41]

Answer:

  339π in³

Step-by-step explanation:

The amount of water is the difference between the volume of the cylinder and the volume of the ball. The appropriate volume formulas are ...

  cylinder V = πr²h

  sphere V = (4/3)πr³

For the given numbers, the volumes are ...

  cylinder V = π(5 in)²(15 in) = 375π in³

  sphere V = (4/3)π(3 in)³ = 36π in³

The water volume is the difference of these ...

  water volume = cylinder V - sphere V

     = 375π in³ - 36π in³ = 339π in³
