Answer:
The radius is decreatsing at a rate 0.78 cm per second.
Step-by-step explanation:
We are given the following in the question:
Instant radius,r = 2 cm
Instant length,l = 9cm
The radius of the cylinder decreases.
Volume of cylinder =
Since the volume of the cylinder does not changes, we can write:
Rate of change of volume:
Puttiung values, we get
Thus, the radius is decreatsing at a rate 0.78 cm per second.
Step-by-step explanation:
if the area of each face of a cubical solid is 1764 CM square find its length
Answer: 2.46
Step-by-step explanation:
Formula for x-score is given by :-
, where = Sample mean , = population mean, = population standard deviation, n= sample size.
As per given , n=10
= $29,056
= $3,339
= $31,650
Then,
Hence, the z-score = 2.46
So what you want to do is draw a circle, then draw one straight across the middle and then one straight top to bottom! :)
Answer:
x = 12°
Step-by-step explanation:
total interior angle of triangle is 180°
so, 10x -11 + 3x+ 1 + 3x -2 = 180
16x-12 =180
16x = 192
x = 12°
