the third one
Answer:
A) 5.4 cm
Step-by-step explanation:
Length of mid segment = (sum of parallel sides )/2
Sum of parallel sides = PQ + SR = 9 + SR
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 .
There is no picture given but I’m assuming you need to simplify it. The answer is 9x + 12
