A= {1, 3, 5, 7, 9}
b = {2, 4, 6, 8, 10}
c = {1, 5, 6, 7, 9}
a ∩ (b ∩ c) =
a.){1, 3, 5, 6, 7, 9}
b.){1, 2, 3, 4, 5, 6, 7, 8, 9, 10}
c.){}

The correct option is C) { }

Step-by-step explanation:

The given sets are:

A = {1, 3, 5, 7, 9}

B = {2, 4, 6, 8, 10}

C = {1, 5, 6, 7, 9}

We need to find A ∩ (B ∩ C)

Since intersection '∩' means common number between those sets

First find (B ∩ C)

(B ∩ C) = 6

now take intersection with A

A ∩ (B ∩ C) =

Hence, A ∩ (B ∩ C) is null set

Therefore, The correct option is C) { }

im alright what do you need

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 !
