I think it’s 4 m because diameter is 2r
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 .
Can you add the price of the tickets?
X = 0.4/3
x = 13
if answer is wanted in decimal form.
The answer is D. The result from the first cube can't affect what you get. In fact, if you had 1 cube and you threw it twice, the second result would still be independent from the first result.
