ANSWER :

a. {2, 6, 9}

b. {6}

EXPLANATION :

From the problem, we have the sets :

\begin{gathered} U=\lbrace2,3,4,6,9\rbrace \\ A=\lbrace2,3,4\rbrace \\ B=\lbrace3,4,6\rbrace \end{gathered}

A' denotes the elements that are NOT present in A but present in U.

B' denotes the elements that are NOT present in B but present in U.

That will be :

\begin{gathered} A^{\prime}=\lbrace6,9\rbrace \\ B^{\prime}=\lbrace2,9\rbrace \end{gathered}

a. A' ∪ B'

The symbol ∪ denotes the union of two sets.

That will be :

A^{\prime}\cup B^{\prime}=\lbrace2,6,9\rbrace

b. A' ∩ B

The symbol ∩ denotes the intersection or common elements of the two sets

That will be :

A^{\prime}\cap B^=\lbrace6\rbrace

2. An empty ice cream cone has a height of 3.02 inches and a radius
ololo11 [35]

Answer:

Approximate volume of ice cream = 3.03 inches

Step-by-step explanation:

Given - An empty ice cream cone has a height of 3.02 inches and a radius

of 0.98 inches.

To find - What is the approximate volume of ice cream it will  hold within the cone  ?

Proof -

We know that,

Volume of the cone = \frac{1}{3}\pi r^{2}h

where

r is the radius of the cone

h is the height of the cone

Here,

Given that,

r = 0.98 inches

h = 3.02 inches

So,

Volume = \frac{1}{3}\pi r^{2}h

             = \frac{1}{3}(3.14) (0.98)^{2}(3.02)         ( Consider the value of \pi = 3.14)

             = 3.0373

∴ we get

Approximate volume of ice cream = 3.03 inches

So,

The correct option is - G. 3 in 3
