Answer:

Step-by-step explanation:
The given equation is 4 + 2/3 x = -5
Taking variable on one side and constants on other side, we get


The number in decimal form is given by -13.5
The number in fraction form is given as 
Answer:
The diameter is 16.8
Step-by-step explanation:
The diameter is double the radius.
Here, you would complete it with the Pythagorean Theorem.
So, A^2 + B^2 = C^2
So 14^2 + B^2 = 14^2
This equals = B = 11.49

From the diagram, we can see that the radius of the cone is 8cm and the height of the cone is 15cm. We then just plug these numbers into the formula and simplify:

The volume of the cone is approximately 1005.3096 cm^3. With 3 sig figs, this is 1010 cm^3.
