Answer:
3.
The length x width is the area so we have to replace it with the area of the cylinder.
The area of a circle is pi x radius^2
Hope this helps
Step-by-step explanation:
Answer:
1) ΔACD is a right triangle at C
=> sin 32° = AC/15
⇔ AC = sin 32°.15 ≈ 7.9 (cm)
2) ΔABC is a right triangle at C, using Pythagoras theorem, we have:
AB² = AC² + BC²
⇔ AB² = 7.9² + 9.7² = 156.5
⇒ AB = 12.5 (cm)
3) ΔABC is a right triangle at C
=> sin ∠BAC = BC/AB
⇔ sin ∠BAC = 9.7/12.5 = 0.776
⇒ ∠BAC ≈ 50.9°
4) ΔACD is a right triangle at C
=> cos 32° = CD/15
⇔ CD = cos32°.15
⇒ CD ≈ 12.72 (cm)

Well, first thing's first: find the area.
The formula for area is L*W
L=9 ft
W=6 ft
9*6=54 sq ft
Since the area is 54 sq ft, and each small glass square is 1 sq ft, you would need A) 54 squares of glass
