"As shown" ?  You have a picture to work with but you're not sharing it ?

Fortunately, the question includes all the information that's needed to answer it,
so I don't need to see the picture.

The volume of a cylinder is (pi) x (radius)² x (height) .

Radius = 1/2 of the diameter = 15 mm

Volume = (pi) x (15 mm)² x (30 mm) = 6,750 pi mm³ = 21,205.75 mm³ .

That's a correct answer, but the number is slightly awkward and inconvenient.  Let's
change it to a bigger unit, so the number will be smaller and easier to carry around.

Remember that 10 mm = 1 cm

So (10 mm)³ = 1,000 mm³ = 1 cm³

and 21,205.75 mm³ = 21.20575 cm³

Questions:
My name is Ann [436]

The  solution to the expressions given are;

9 -9t/ 12 - 5t

a. 20/ 169

b. -170/ 169

c.  386/ 169

d.  -10/ 169

<h3>How to solve the expressions</h3>

Given:

\frac{9 - 19t}{12 - 5t}

We can see that both variables in the numerator and denominator have no common factor, thus cannot be factorized further

a. \frac{203}{169} - \frac{183}{169}

First, let's find the lowest common multiple

LCM = 169

= \frac{203 - 183}{169}

= \frac{20}{169}

= 20/ 169

b. \frac{13}{119} - \frac{183}{119}

The lowest common multiple is 119

= \frac{13 - 183}{119}

substract the numerator

= - 170/ 119

c. \frac{203}{169} - \frac{183}{169}

The lowest common multiple is 169

= \frac{203 + 183}{169}

= 386/ 169

d. \frac{9}{169}- \frac{19}{169}

The lowest common multiple is 169

= \frac{9 - 19}{169}

= - 10/ 169

Thus, we have the solutions to be 9 -9t/ 12 - 5t, 20/ 169, -170/ 169, 386/ 169, -10/ 169 respectively.

Answer:

1: -7

2: -7

3:-7

4: 8

5: 8

6: 8

Step-by-step explanation:

for the first one, you do 6-1=5 and then times that by 2 and then simplify that to get -7. for the second one, you do 2^{3} which is 8+4=12, and divide 24 by that to get 2 and minus nine to get -7. for the 3rd one, you do 4^{2}+9 first (16+9)= 25, and subtract 39 from that to get 14, then do 4-5=-1 *2=-2, which gets you -7. for 4 , you do 81-25= 56 over 10+8-11=7 which gets you 8. for 5, you do 36-20=16  in parentheses first and then divide 48 by that to get 3 and subtract that to get 8. last, for 6, you do 22-14 to get you 8
