Answer:

$\boxed{\sf 200\pi}$

Step-by-step explanation:

We know that the volume of a cone:-

$\boxed{\sf \pi r^2\cfrac{h}{3}}$

(r = 10) (h = 6)

$\sf \pi \times 10^2\times\cfrac{6}{3}$

<u>Divide numbers:-</u>

$\sf \cfrac{6}{3}=\boxed{2}$

$\sf 10^2\times \:2\pi$

$\sf 100\times \:2\pi$

<u>Multiply numbers:-</u>

$\boxed{\sf 200\pi}$

Therefore, your answer is 200π³

We could also multiply 200 by 3.14 which will give you 628 units³.

For which angle O is cos 0 = -1?

REY [17]

Answer:

540 degrees

Step-by-step explanation:

The cosine of an angle on a unit circle yields the x value. Therefore, wherever the x value is -1, cos O is -1. Cosine is equal to -1 at 180 degrees, and every 360 degree interval after that. Since 180 degrees is not an option, we need to try the next interval of 360. 180+360=540 degrees, which is one of the options. Hope this helps!
