Answer:
The formula for finding volume of a cone is (in this case),
V=(3.14)(r^2)(h/3)
With this formula in mind, you would simply substitute in.
V=(3.14)(2^2)(9/3)
You could work that out for yourself on your own, but to save you the time, it is 37.68 in. cubed.

Step-by-step explanation:
Answer:
Number of coefficients of x: 2 coefficients (-4 and 3)
Number of terms: They're 4 terms. (-4x, -2, + 3x, and -10)
Simplified: - x - 12
Step-by-step explanation:
1) Subtract the numbers.
-4x - 12 + 3x
2) Combine like terms.
- x - 12
The answer to this is A. i just asked that
Answer: The length of the is 4.5 cm when the measure of the central angle is 162 degrees.
If the measure of the central angle is 162 degrees, that means that is comprises 45% of the circle. 162 / 360 = 45%
Therefore, the arc is also 45% of the circumference. If we multiply 10 by 45% we get an arc length of 4.5 cm.
