The answer is 54πx² + 144πx + 96π
The surface area of cylinder (SA) is:
SA = 2 π r h + 2 π r²
<span>The height of the gift box is twice the radius: h = 2r
r = 3x + 4
h = 2(3x + 4) = 6x + 8
SA = </span>2 π r h + 2 π r²
SA = 2π (r * h + r²)
SA = 2π ((3x + 4)(6x + 8) + (3x + 4)²)
SA = 2π(18x² + 24x + 24x + 32 + 9x² + 24x + 16)
SA = 2π(27x² + 72x + 48)
SA = 54πx² + 144πx + 96π
Given the value of t3 and t7, and t7 = t3 * r^4, where r represents the geometric quotient.
So 7104 = 444 * r^4 -> solve for r, you will get r = 2 or -2
So, for r = 2, t6 = t7 / r = 7104 / 2 = 3552
For r = -2, t6 = -3552
Answer:
∠2=92°
Step-by-step explanation:
Using an angle formula, -8x+144=2x+74
Simplification:
-8x+144=2x+74
-8x+70=2x
70=10x
x=7
Therefore, each angle is 88°
Now, because ∠2 is adjacent to one of 88°, they add up to 180°
Therefore,
180°=88°+∠2
∠2=92°
The results of the survey will most likely suffer from wording bias.
<h3><u>Wording Bias</u></h3>
The question asked in the survey contains certain characteristics that induce the respondent to think about the question asked in a negative way.
Thus, the word "wasteful" induces respondents to answer the question bearing in mind the negative criticism made by the questioner, which may influence the final answer.
