The sum of angles in triangle is equal to 180 degrees, so
<R =180-56-30
<R=94

Step-by-step explanation:
Answer: 1:1
Step-by-step explanation:
Let r be the radius and h be the height of a cylinder.
Formula: Curved surface area of cylinder = 
Now, if radius of a cylinder is doubled and its height is halved, then new radius will be R= 2r and new height will be 
Now, new surface area = 
Ratio of curved surface areas : 
Hence, the ratios of their surface areas = 1:1 .
1/2. You would round 3/8 to 1/2 to 0. Then you add 1/2 to 0 and you get your answer.
If you want an answer greater that 7, your fraction needs to be greater than 1.
n can be any number greater than 4
