A cylinder is being flattened so that its volume does not change. Find the rate of change of radius when r = 3 inches and h = 5 inches, if the height is decreasing at 0.6 in/sec. Hint: what is the rate of change of volume?

The radius is increasing at a rate 0.18 inches per second.

Step-by-step explanation:

We are given the following in the question:

The volume of cylinder is constant.

Instant radius= 3 inches

Instant height = 5 inches

Volume of cylinder =

Rate of change of volume =

Putting all the values, we get,

Thus, the radius is increasing at a rate 0.18 inches per second.

correct answer is b. 27/8

step-by-step explanation:

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
