Answer:
12.8 cm
Step-by-step explanation:
Radius of the can is 8 cm and height is 20 cm.
It is given that after painting his porch Jamil has of a can of paint remaining. So, first we need to find the total amount of paint in the can.
Total amount of paint in the can is
So, paint in the can
Now of the can is
cubic cm.
Now, let the height of the smaller can be <em>h</em> cm.
Radius of the smaller can is 5 cm.
As, the paint is poured into the smaller can the volume of both the cans will be same.
Hence, height of the smaller can to hold the paint must be 12.8 cm.
Write the set of points from -6 to 0 but excluding -4 and 0 as a union of intervals
First we take the interval -6 to 0. In that -4 and 0 are excluded.
So we split the interval -6 to 0.
Start with -6 and go up to -4. -4 is excluded so we break at -4. Also we use parenthesis for -4.
Interval becomes [-6,-4) . It says -6 included but -4 excluded.
Next interval starts at -4 and ends at 0. -4 and 0 are excluded so we use parenthesis not square brackets
(-4,0)
Now we take union of both intervals
[-6,-4) U (-4,0) --- Interval from -6 to 0 but excluding -4 and 0
