Answer: 4in
Step-by-step explanation:
Volume of a cylinder = πR²H
Volume of a cone = 1/3πr²h
πR²H = 1/3πr²h
π is very common so it could be cancelled, so the equation now becomes
R²H = 1/3r²h
3R²H = r²h
Now substitute for the values
h = 3 x 2² x 3
--------------
3²
= 9 x 4/9
= 4in.
Therefore, the height of the cone
h = 4in.
Isolate the variable Y by multiplying 1.5 on both sides.


Hope this helps.
頑張って!

Step-by-step explanation:
The bottom left, lies never -6 on x axis and 20 on y axis
70 times .9 is 63 so 90 minus 63 is27 so it was $27
