Answer:
4:25
Step-by-step explanation:
Given that,
r₁ = 15 inches, r₂ = 6 inches
The area of the cylinder is given by :

The ratio of surface areas of two cylinders,

Hence, the required ratio is 4:25.
Using law of cosines:
Cos(angle) = adjacent/ hypotenuse
Cos(22) = 12/x
Rewrite to get:
X = 12/cos(22)
Simplify:
X = 12.9424
Round the answer as needed.
Answer:
Total trade discount on 30 boxes = $201.555
Step-by-step explanation:
1 box = $14.93
And a trade discount of 45% is allowed on a single box,
Therefore, the discount on one $14.93 box will be
45% × $14.93 = $6.7185
So, if there are now 30 boxes, the trade discount on all 30 boxes will be
30 × (trade discount on one box) = 30 × ($6.7185) = $201.555
Hope this helps!
