To solve this equation, we need to subtract both, 9c - 3c:

Dividing by 6 at both sides of the equation

Then

Then the answer C = 8. (Option D)
Answer:
Step-by-step explanation:
r = 9 cm
h = 10 cm
Volume of cone = (1/3)πr²h

= 847.8 cubic cm
Answer:
6.5

Answer:
1/6
Step-by-step explanation:
There is only one side of the die with a number 4, and 6 possible outcomes. Therefore the answer is 1/6
Replace x with 3:
9.96(5)^3 + 6.38
Simplify
9.96(125) + 6.38
Do the multiplication then addition
1245 + 6.38 = 1251.38
Answer: 1251.38
