Hello there. :)
<span>How many miles are in 400 kilometers
248.548

That is correct.
Sqrt 5 x sqrt20
Apply the radical rule to get sqrt( 5 x 20)
Simplify to get sqrt(100)
Sqrt(100) = 10
Answer:
101.76
Step-by-step explanation:
(12.9−3.1)(6.2)−2+43
=(9.8)(6.2)−2+43
=60.76−2+43
=58.76+43
=101.76
Answer:
The volume is decreasing at a rate 20π cubic meter per hour.
Step-by-step explanation:
We are given the following in the question:
The radius is increasing at a rate 1 meter per hour.
The height is decreasing at a rate 4 meter per hour

At an instant time t,
r = 5 meter
h = 8 meters
Volume of cylinder =

where r is the radius and h is the height of the cylinder.
Rate of change of volume is given by:

Putting all the values we get,

Thus, the volume is decreasing at a rate 20π cubic meter per hour or 62.8 cubic meter per hour.
