I don't know how to solve questions like this. k-10=-7

You have to add 10 to both sides of the equation because you want to have your variable (in this case it's K) to be on it's own. K=-7+10 or K=10-7 Then you subtract 7 from 10 and you get k=3. Let me know if you don't understand.

Lady bird [3.3K]

Answer:

The volume of the figure is 905 cubic units.

Step-by-step explanation:

Rotation is a method of solid transformation which involve turning a given line, or object about a reference point. In the given question, rotating segment AB completely about the y-axis would form a 3 dimensional figure of a sphere.

volume of a sphere = $\frac{4}{3}$ $\pi$ $r^{3}$

where r is the radius of the sphere.

Given that AB = 6, then the radius of the sphere = 6

volume of sphere = $\frac{4}{3}$ x $\frac{22}{7}$ x $(6)^{3}$

= $\frac{88}{21}$ x 216

= 905.14

volume of sphere = 905 cubic units

The volume of the figure is 905 cubic units.
