The surface area of a cylinder is increasing at a rate of 9 pi square meters per hour. The height of the cylinder is fixed at 3

Alekssandra [29.7K]

Answer:

$9\pi \text{ cubic meters per hour}$

Step-by-step explanation:

Since, the surface area of a cylinder,

$A= 2\pi r^2 + 2\pi rh$ ................(1)

Where,

r = radius,

h = height,

If $A= 36\pi\text{ square meters}, h = 3\text{ meters}$

$36\pi = 2\pi r^2 + 2\pi r(3)$

$18 = r^2 + 3r$

$\implies r^2 + 3r - 18=0$

$r^2 + 6r - 3r - 18 = 0$ ( by middle term splitting )

$r(r+6)-3(r+6)=0$

$(r-3)(r+6)=0$

By zero product property,

r = 3 or r = - 6 ( not possible )

Thus, radius, r = 3 meters,

Now, differentiating equation (1) with respect to t ( time ),

$\frac{dA}{dt}= 4\pi r\frac{dr}{dt} +2\pi(r\frac{dh}{dt} + h\frac{dr}{dt})$

∵ h = constant, ⇒ dh/dt = 0,

$\frac{dA}{dt} = 4\pi r \frac{dr}{dt} +2\pi h \frac{dr}{dt}$

We have, $\frac{dA}{dt}=9\pi\text{ square meters per hour}, r = h = 3\text{ meters}$

$9\pi = 4\pi (3) \frac{dr}{dt}+2\pi (3)\frac{dr}{dt}$

$9\pi = (12\pi + 6\pi )\frac{dr}{dt}$

$9\pi = 18\pi \frac{dr}{dt}$

$\implies \frac{dr}{dt} =\frac{1}{2}\text{ meter per hour}$

Now,

Volume of a cylinder,

$V=\pi r^2 h$

Differentiating w. r. t. t,

$\frac{dV}{dt}=\pi ( r^2 \frac{dh}{dt}+h(2r)\frac{dr}{dt})=\pi ((3)(6) (\frac{1}{2})) = 9\pi \text{ cubic meters per hour}$

Which number round to 38,800 when rounded to the nearest hundred

V125BC [204]

There can be so many of such.

Eg. 38 750 38 835

38 795

38 820

Any of the numbers above when rounded to the nearest hundred would result in 38 800.

The idea is such that to make sure the 100 digit is 7 and the 10 digit is 5 or more.

Or if the 100 digit is already 8, then the 10 digit must be less than 5

Write a summary of the poem "Revenge"

Tresset [83]

Answer:

I was angry with my friend;

I told my wrath, my wrath did end.

I was angry with my foe:

I told it not, my wrath did grow.

And I waterd it in fears,

Night & morning with my tears:

And I sunned it with smiles,

And with soft deceitful wiles.

And it grew both day and night.

Till it bore an apple bright.

And my foe beheld it shine,

And he knew that it was mine.

And into my garden stole,

When the night had veild the pole;

In the morning glad I see;

My foe outstretched beneath the tree.
