Answer:

I'll answer 6 to 10 cuz that's only what I'm able to see

Step-by-step explanation:

Y-Z

= {6,4,7,2,8,3} - {2,7,8,9,10}

= {6,4,3}

( Y ∪ Z ) ∩ X

= ( {6,4,7,2,8,3} ∪ {2,7,8,9,10} ) ∩ {1, 2,3,5,8}

= { 2,3,4,6,7,8,9,10} ∩ {1, 2,3,5,8}

= {2,3,5,8}

( X ∪ Y ) ∩ ( Y ∪ Z )

= ( {1, 2,3,5,8} ∪ {6,4,7,2,8,3} ) ∩ ( {6,4,7,2,8,3} ∪ {2,7,8,9,10} )

= {1,2,3,4,5,6,7,8} ∩ {2,3,4,6,7,8,9,10}

= {2,3,4,6,7,8}

( X ∩ Z ) ∪ ( X ∩ Y )

= ( {1,2,3,5,8} ∩ {2,7,8,9,10} ) ∪ ( {1,2,3,5,8} ∩ {6,4,7,2,8,3} )

= {2,8} ∪ {3,8}

= {2,3,8}

10.

( X ∪ Y ) ∩ Z

= ( {1,2,3,5,8} ∪ {6,4,7,2,8,3} ) ∩ {2,7,8,9,10}

= {1,2,3,4,5,6,7,8} ∩ {2,7,8,9,10}

= {2,7,8}

Which term in this expression is a constant?<br><br> 6a + a + 3b + 18

MrMuchimi

The constant would be 18, mostly because the constant is revealed to be a number alone rather than a number times an unknown number.

Find the volume of the cylinder with a radius of 16 mm and a height of 30 mm

Luda [366]

Answer:

6,031 <em>using diameter, not radius</em>

$V = \pi * (\frac{16}{2})^2 * 30 = 6,028.8$

Which rounds closest to

6,031
