The radius of a right circular cylinder is increasing at the rate of 3 ft/sec, while the height is decreasing at the rate of 6 f

goblinko [34]

Answer:

$\frac{dV}{dt}=-450\pi ft^3/sec$

Step-by-step explanation:

Let's assume

radius of cylinder as 'r'

height of cylinder as 'h'

so, we have

$\frac{dr}{dt} =3ft/sec$

$\frac{dh}{dt} =-6ft/sec$

r=15ft

h=10ft

now, we can use volume of cylinder formula

$V=\pi r^2h$

we can find derivative with respect to t

$\frac{dV}{dt}=2\pi r h\times\frac{dr}{dt} +\pi r^2\times \frac{dh}{dt}$

now, we can plug values

$\frac{dV}{dt}=2\pi (15)(10)\times3 +\pi (15)^2\times -6$

now, we can simplify it

$\frac{dV}{dt}=-450\pi ft^3/sec$

Is my solution correct?

Answer:

The area of the shaded sector is $51.2\pi \ units^{2}$

Step-by-step explanation:

I assume that the problem is

Find the area of the shaded sector of the circle with radius equal to 16 units

step 1

Find the value of x

we know that

$8x+2x=360\°$ -----> by complete circle

$10x=360\°$

$x=36\°$

The central angle of the shaded sector is 2x

$2(36\°)=72\°$

step 2

Find the area of the circle

The area of the circle is equal to

$A=\pi r^{2}$

we have

$r=16\ units$

substitute

$A=\pi (16)^{2}$

$A=256\pi\ units^{2}$

step 3

Find the area of the shaded sector

we know that

A central angle of 360 degrees subtends an area of circle equal to $256\pi\ units^{2}$

so

by proportion

Find the area of the shaded sector by a central angle of 72 degrees

$\frac{256\pi}{360}=\frac{x}{72} \\ \\ x=256\pi *(72)/360\\ \\x=51.2\pi \ units^{2}$
