Find the volume - leave answer in terms of π

Andreas93 [3]

Answer:

144 $\pi$

Step-by-step explanation:

Volume of a Sphere :

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

V = $\frac{4}{3}$ $\pi$ $6^{3}$

V = $\frac{4}{3}$ (216) $\pi$ (216 times 4, divided by 3)

V = 288 $\pi$

Now divide by 2, it's only half of a sphere.

C=-a/b what does a equal

Nutka1998 [239]

Answer:

a = -bc

Step-by-step explanation:

We are given the equation:

c = -a/b

Because multiplication and division are inverse operations, if we move b over to the other side, since it was dividing on the right side, it would be multiplied on the other side (I don't know how to explain that well)

so you can make it look like this:

b*c = -a

Or:

-a = b*c

Then, do isolate a, we will have to divide by -1 on both sides

a = -b*c

To check this, we can plug in numbers

-8 = -16/2

-16 = -8*2

16 = 8 * 2

Let me know if you have any questions
