What is the cube root of 216x9 y18 ? a. 4x3 y6 b. 6x3 y6 c. 72x6 y15 d. 213x6 y15

Option B.

6*(x^3)*(y^6)

Step-by-step explanation:

Please see attached picture for the answer to the problem

We know that

6^3 = 216

So,

∛216 = 6

∛x^9 = x^3

∛y^18 = y^6

And,

∛216*∛x^9*∛y^18 = ∛(216*x^9*y^18)

{3 + i, 3 - i, 3, -1}

step-by-step explanation:

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
