Answer:
Volume of bottom of cylinder = Volume of entire cylinder - Volume of top of cylinder
Step-by-step explanation:
Here we have the volume of a cylinder given by
Volume of a cylinder = πr²h
Where the cylinder is cut by a plane into portions of heights, bottom a and top b we have
Height of bottom of is then
Height = h - b
Therefore, volume of bottom of cylinder = π·r²h = π·r²(h - b)
Volume of bottom of cylinder = π·r²·h - π·r²b
Volume of bottom of cylinder = Volume of entire cylinder - Volume of top of cylinder.
Ans given below
-3r-12=-21
-3r=-21+12
-3r=-9
r=-9\-3
r=3
It will be 1062000 because....
you multiply 202400 by 5
the key word in the reading is times
Do you think you can send a picture of the problem I’m not really understanding
