If a central angle of measure 30° is subtended by a circular arc of length 6 meters, as is illustrated below, how many meters in

length is the radius of the circle?

30 degrees = pi/6 radians
Arc Length = (radius)(angle in radians)
6 = (radius)(pi/6)
radius = 36/pi or approx. 11.5 m

The surface area of a sphere is increasing at a rate of 14\pi14π14, pi square meters per hour. At a certain instant, the surface

Sauron [17]

Answer:

$21\pi$ cubic meters per hour

Step-by-step explanation:

We know that the surface area of a sphere is,

$A=4\pi r^2$ ...........(1),

Where,

r = radius of the sphere,

We have, A = $36\pi$ square meters,

$36\pi = 4\pi r^2$

$9 = r^2$

$\implies r = 3\text{ meters}$

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

$\frac{dA}{dt} = 8\pi r\frac{dr}{dt}$

We have,

$\frac{dA}{dt}=14\pi\text{ square meters per hour}, r = 3\text{ meters}$

$14\pi = 8\pi (3) \frac{dr}{dt}$

$\frac{14}{24}=\frac{dr}{dt}$

$\frac{7}{12} = \frac{dr}{dt}$

Also, the volume of a sphere is,

$V = \frac{4}{3}\pi r^3$

Differentiating with respect to t(time)

$\frac{dV}{dt}=4\pi r^2\frac{dr}{dt}$

By substituting the values,

$\frac{dV}{dt}=4\pi (3)^2 (\frac{7}{12})=36\pi \frac{7}{12}=21\pi\text{ cube meters per hour}$

Hence, the rate of change of the volume of the sphere at that instant would be $21\pi$ cubic meters per hour

2x-2=10x+ 20<br> How do I solve for x

kramer

Answer:

16

Step-by-step explanation:

2x -2 = 10 + 20

2x -2 + 2= 10 + 20 + 2

2x = 32

x = 32/2 = 16

Plug this in, too.

2(16) - 2 = 10 + 20

30 = 30 and they are equal!
