Answer:
x is 64 degrees
Step-by-step explanation:
Since the polygon is a quad we know all the angles add up to 360. So, we can do :
100 + 130 + 66 = 360 - x
296 = 360 - x
Subtract 360 on both sides
-64 = -x
Multiply by negative one on both sides and we get
64 = x
x is 64 degrees

Answer:
8000π mm^3/s ≈ 25,133 mm^3/s
Step-by-step explanation:
The rate of change of volume is found by differentiating the volume formula with respect to time.
V = 4/3πr^3
V' = 4πr^2·r'
For the given numbers, this is ...
V' = 4π(20 mm)^2·(5 mm/s) = 8000π mm^3/s ≈ 25,133 mm^3/s
_____
<em>Additional comment</em>
By comparing the derivative to the area formula for a sphere, you see that the rate of change of volume is the product of the area and the rate of change of radius. This sort of relationship will be seen for a number of different shapes.
easy 214.7 because if it was rounded it would be 214.700 an this is way bigger than 214.275
