The answer to this question is B. 130cm^2.

Using the volume formula for a sphere (V = (4/3)πr^3) you can plug in the values that we know to find the radius to be around 3.22117 cm. You can then use the area of a sphere formula (A = 4πr^2) to find the area. Hope this helps :)

Answer:

Step-by-step explanation:

Remark

A B and D refer to what the cylinder can contain. They all refer to the hollowed out part of the cylinder.

C is the only one that talks about what you need to cover the cylinder with (say) paper or cloth. C is external to the surface of the cylinder.

Answer:

See image

Step-by-step explanation:

To graph the inequality

-2x + y >= -10

Change it to y = mx + b form, use a solid line (bc of the "or equal to" underline)

y >= 2x - 10 We have y-intercept at -10 and slope 2/1, shading goes above the line.

The other graph is an absolute value graph; it has a v-shape. The 7 makes it stretched 7 times taller (and skinnier) the -4 by the x shifts the whole graph to the right 4 units. The -4 at the end of the equation shifts the whole graph down 4 units. See image. The shading goes above the V (kind of looks like inside)

The solution to the system is where the shading of the two overlap. It is mostly the shading for the absolute value graph except for a tiny triangle at the bottom. See image.

How to solve for b in the following equation...<br><br> 53.2=30.5b^50
Margarita [4]

Answer:

  b = (53.2/30.5)^(1/50) ≈ 1.011188765

Step-by-step explanation:

Divide by the coefficient of the variable, then take the 50th root.

  53.2/30.5 = b^50

  (53.2/30.5)^(1/50) = b . . . . . . 50th root of both sides of the equation

__

You know the rule of exponents for powers of powers is ...

  (a^b)^c = a^(bc)

If we want bc = 1, then we must have c = 1/b.
