Answer:
The surface area of this cylinder. is <em><u>266π cm²</u></em>
Step-by-step explanation:
Surface Area of Cylinder (SA) = 2πrh+2πr²
since r = 7cm & h = 12 cm
Then SA = 2 π (7)(12) + 2π(7²)
SA = 168π + 98π
∴ SA = 266π cm²
226pi
2 * pi * 7 *(7+12)
The wright answer is 16.33 inches
The width of the cooling tower at the base of the structure will be A. 36 meters.
From the information given, the towers walls are modeled by x²/324 - (y² - 90)²/1600.
Therefore, the width of the cooling tower at the base of the structure will be:
= 2 × ✓324
= 2 × 18
= 36
In conclusion, the width is 36 meters.

The greatest common factor would be 12.
24: 1, 2, 3, 4, 6, 8, <u><em>12</em></u>, 24
60: 1, 2, 3, 4, 5, 6, 10 , <u><em>12</em></u>, 15, 20, 30, 60
Hope it helps!
rate of change= x= 4 y= 20
slope= rise/run= change in y values/change in x values
slope= 20/4
i believe this is right, i could be wrong, i haven't done it in a long time.
