Hello!
The cylinder shown has a lateral surface area of about 80 square inches. Which answer is closest to the height of the cylinder? Use 3.14 to approximate pi.
We have the following data:
Al (lateral surface area) = 80 in²
R (ratio) = 4 in
h (height) = ? (in inches)
Adopt : π ≈ 3.14
We apply the data to the formula, we have:
![A_l = 2*\pi*R*h](https://tex.z-dn.net/?f=A_l%20%3D%202%2A%5Cpi%2AR%2Ah)
![80 = 2*3.14*4*h](https://tex.z-dn.net/?f=80%20%3D%202%2A3.14%2A4%2Ah)
![80 = 25.12\:h](https://tex.z-dn.net/?f=80%20%3D%2025.12%5C%3Ah)
![25.12\:h = 80](https://tex.z-dn.net/?f=25.12%5C%3Ah%20%3D%2080)
![h = \dfrac{80}{25.12}](https://tex.z-dn.net/?f=h%20%3D%20%5Cdfrac%7B80%7D%7B25.12%7D)
![h = 3.18 \to \boxed{\boxed{h \approx 3.2\:in}}\:\:\:\:\:\:\bf\green{\checkmark}](https://tex.z-dn.net/?f=h%20%3D%203.18%20%5Cto%20%5Cboxed%7B%5Cboxed%7Bh%20%5Capprox%203.2%5C%3Ain%7D%7D%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5C%3A%5Cbf%5Cgreen%7B%5Ccheckmark%7D)
Answer:
≈ 3.2 inches

i used a calculator, to the nearst tenth is 0.18 to the nearest 100th is 0.185 also the 185 is repeating so u put a line over the numbers 185
Answer:
1041.27
Step-by-step explanation:
A=πrl+πr2
l=r2+h2
Solving forA
A=πr(r+h2+r2)=π·12·(12+102+122)≈1041.26829
Answer:
Step-by-step explanation:
I think the quotent is 5, but I recommend waiting for sumone else to answer. Because 31.5 divided by 1.4 equals 22.5 but I'm not sure.
