Hi there!
The formula for the volume of a cone is V = 1/3(pi x r^2 x h). Using this formula, we can solve for the volume of the cone.
WORK:
V = 1/3(3.14 x 6.5^2 x 14)
V = 1857.31 / 3
V = 619.10 cm^3
ANSWER:
A) 619.10cm^3
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
Answer:
99
Step-by-step explanation:
-6-5[-4-(6+12)]+(-5)
Following PEMDAS
We work the parentheses from the inside out
-6-5[-4-(18)]+(-5)
-6-5[-22]+(-5)
Now we multiply
-6+110 -5
Now we add and subtract from left to right
104 -5
99
Your answer should be 76/45
The easiest way to tell whether lines are parallel, perpendicular, or neither is when they are written in slope-intercept form or y = mx + b. We will begin by putting both of our equations into this format.
The first equation,

is already in slope intercept form. The slope is 1/2 and the y-intercept is -1.
The second equation requires rearranging.

From this equation, we can see that the slope is -1/2 and the y-intercept is -3.
When lines are parallel, they have the same slope. This is not the case with these lines because one has slope of 1/2 and the other has slope of -1/2. Since these are not the same our lines are not parallel.
When lines are perpendicular, the slope of one is the negative reciprocal of the other. That is, if one had slope 2, the other would have slope -1/2. This also is not the case in this problem.
Thus, we conclude that the lines are neither parallel nor perpendicular.
