Answer:
791.28
Step-by-step explanation:
1. 3.14*9²=254.34
2. 3.14*9*19=536.94
3. 536.94+254.34=791.28

Answer:x-coordinate of point w is nearly -3.5
Explanation:To get the x-coordinate of a certain point, we would need to read the value of this point on the horizontal axis (the x-axis).
Taking a look at point w, we would find that it is in the second quadrant. This means that it has a negative x-value.
Now, reading the x-value on the horizontal axis, we can see that it is nearly midway between points -3 and -4.
This means that point w is approximately -3.5
Hope this helps :)
Answer:
b=1/2-9/4c
Step-by-step explanation:
first get B on one side
8b+18c=4
-18c -18c
8b=4-18c
divide both sides by 8
8b=4-18c
/8 /8 /8
b=1/2-9/4c
Since we are dealing with a volume problem (3 dimensions) when you increase the radius by a factor of 2, you increase the volume by a factor of 2^3 or 8
So, the larger sphere has a volume 8 times greater than the smaller sphere.
