Answer:

Here the error is

[tex]\pi {r}^{2} [/tex]

It should have been ,

[tex]2\pi {r}^{2} [/tex]

Step-by-step explanation:

Corrected formula:

[tex]2\pi {r}^{2} + 2\pi rh[/tex]

[tex] = 2\pi ({5}^{2}) + 2\pi(5)(10.6)[/tex]

[tex] = 50\pi + 106\pi[/tex]

[tex] = 156\pi[/tex]

[tex] = 489.84 {yd}^{2} [/tex]

[tex]approx . \: 489.8 {yd}^{2} (ans)[/tex]

Joe wants to paint a diagonal line across a sign over the door of his office. The sign measures 8 ft. by 6 ft. How long will the diagonal line be?

Answers

the line would be 48 feet long because 6x8 = 48

Answer:

10 ft.

Step-by-step explanation:

By using the pytahgorean theorem a² + b² = c² we can determine the answer of 10 ft. If you do not know already the length and width are the a and the b so a=6 and b=8. by squaring both of these we get a=36 and b=64 (squaring is just the number times itself so 3² would be 3x3) by adding both of these squared values we get 64+36=100 which means that c²=100 so to get our final answer we just take the square root of c² which is the opposite of squaring it. So √100=10 and that is our final answer

B. 12
C. 14
D.16

Answers

Answer:

B, 12

Step-by-step explanation:

there are many ways to solve this problem, I will state 2:

divide 36 by 3, your answer would be 12

simply multiply 3 by each number on the question, your answer as well will be 12.

which of these would be a helpful first step in solving the equation? check all that apply. 7x - 9 = 2x + 21

Answers

Answer: E. Subtract 2x

Step-by-step explanation:

Subtracting 2x would remove a bit from both equations, giving us 5x - 9 = 12. This would make it easier now that we only have one number on a side.

Hope this helps!
