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.
56x² - 49x + 14 = 7(8x² - 7x +2)
_____
The greatest common factor of 56, 49, and 14 is 7.
Answer:
C
Step-by-step explanation:
Plug 1, 2, and 3 into n and you'll get 15, 13, and 11 respectively
X=$30
y=$60
1 hour job- 60x1=60+30=90
3 hour job-60x3=180+30=210
