The radius of the base of a cylinder is decreasing at a rate of 9 millimeters per hour and the height of the cylinder is increas

Answer:

<em>Answer: d) -310pi</em>

Step-by-step explanation:

<u>Instantaneous Rate of Change</u>

Is the change in the rate of change of a function at a particular instant. It's the same as the derivative value at a specific point.

The surface area of a cylinder of radius r and height h is:

$A=2\pi r^2+2\pi r h$

We need to calculate the rate of change of the surface area of the cylinder at a specific moment where:

The radius is r=8 mm

The height is h=3 mm

The radius changes at r'=-9 mm/hr

The height changes at h'=+2 mm/hr

Find the derivative of A with respect to time:

$A'=2\pi (r^2)'+2\pi (r h)'$

$A'=2\pi 2rr'+2\pi (r' h+rh')$

Substituting the values:

$A'=2\pi 2(8)(-9)+2\pi ((-9) (3)+(8)(2))$

Calculating:

$A'=-288\pi +2\pi (-27+16)$

$A'=-288\pi +2\pi (-11)$

$A'=-288\pi -22\pi$

$A'=-310\pi$

Answer: d) -310pi

Someone please help I’m so confused

Veronika [31]

Answer:

80 - 12 - 5f

Step-by-step explanation:

You have a total of eighty seeds in all.

Minus the twelve seeds Demi planted.

The number of friends she gave seeds to is unclear.

To find out how many seeds she gave you'd have to

multiply five by the number of friends.

It's is all being subtracted from the total.

Hope this helps. ;)
