The original surface area is:
A = 2 * pi * r ^ 2 + 2 * pi * r * h
Where,
r: radio
h: height
The area when the dimensions are modified is:
A '= 2 * pi * (4r) ^ 2 + 2 * pi * (4r) * (4h)
Rewriting we have:
A '= 16 * 2 * pi * r ^ 2 + 16 * 2 * pi * r * h
A '= 16 (2 * pi * r ^ 2 + 2 * pi * r * h)
A '= 16A
Answer:
the new surface area would be 16 times bigger than the original surface area
The correct answer for this question is this one: "The square root of terms separated by addition and subtraction cannot be calculated individually."
<span>The statement that best explains why the expression cannot be rewritten as during the next step is that t</span>he square root of terms separated by addition and subtraction cannot be calculated individually.
Hope this helps answer your question and have a nice day ahead. ..... hope that helps
-7 is your answer to this equation
Answer:
y=2x−3
⇒−1=2a−3
⇒2a=−1+3=2
∴a=22=1
y=2x−3
b=2×5−3
⇒b=10−3=7
∴b=7

The answer is 180ft squared. I got this when I used the formula 1/2 times base times height
equation 1/2 timed 20 times 18
- u can divide half of 20 or 18
10 times 18 = 180
