What is percentage change?

By quantifying the difference between two numbers and expressing it as an increase or decrease, the Percentage Change Calculator (percent change calculator) may determine the percentage change.

The initial price $V_{1}$ (100%) was decreased by 10%., then this reduced price is reduced more by 20% that becomes the final price $V_{2}$ which is 72.

Calculate percentage change from $V_{1}=100$ to $V_{2}=72$ .

= $& \frac{\left(V_{2}-V_{1}\right)}{\left|V_{1}\right|} \times 100 \\$

$=& \frac{(72-100)}{|100|} \times 100 \\$

$=& \frac{-28}{100} \times 100 \\$

$=&-0.28 \times 100 \\$

$=&-28 \% \text { change } \\$

$=& 28 \% \text { decrease }$

<h3>Answer: 282.6 square units</h3>

====================================================

Work Shown:

r = 3 is the radius of the circular base

h = 12 is the height of the cylinder

pi = 3.14 approximately

SA = surface area of the cylinder

SA = 2pi*r^2 + 2pi*r*h

SA = 2*3.14*3^2 + 2*3.14*3*12

SA = 282.6

Answer: 2z-15

Step-by-step explanation

Based on the visual image, AD is a line where a point O intersects somewhere on the line. AD is represented as 3z-11, while the segment from AO is represented as z+4.

In order to find the answer, we must subtract the entire line (AD) from AO in order to find the missing segment OD.

AD - AO = OD

(3z-11) - (z+4) = OD

Distribute the negative sign so it becomes:

(3z-11) -z - 4 = OD

Now combine like terms.

(3z-z) +(- 11 -4)= OD

2z - 15 = OD

And that is your answer!
