Answer:
Volume = 434.89276543154 inch³
Step-by-step explanation:
volume = 4/3πr³
where r is the radius
r = 9.4/2
r = 4.7³
Volume = 4/3×π×4.73³
Volume = 434.89276543154 inch³
The answer to the first question
is 2 1/4.
The answer to the second question is 8 sqroot 3. Hope I was able to help
Answer:
about 16°
Step-by-step explanation:
Make sure your calculator is in degree mode.
Drawing the right triangle, we see that the shorter leg is 34 meters, and the longer leg is 122 meters. So the angle of elevation is:
Answer:
I would think it would be C. because there is not other answer.
I hoped this help.
please mark brainliest if correct
7.) the equation of the circle is
(x - 3)^2 + (y - 4)^2 = 25
If you substitute the point in you get
(6-3)^2 + (8-4)^2 = 25
3^2 + 4^2 = 25
9 + 16 = 25
25 = 25
Both sides of the equation are the same so it proves it lies on the circle
8.) you add the x coordinates together and divide by 2
7 + 4 = 11
11/2 = 5.5
You use +7 because you need to find the midpoint.
You then add 5.5 to - 7 or - 5.5 from 4
-7 + 5.5 = - 1.5
You do the same for y coordinates
6+5 = 11
11/2 = 5.5
6-5.5 = 0.5
So the coordinates of Rachel's house are
(-1.5, 0.5)
