AB²=5²+5²+5²=25+25+25=75
AB=5√3≈8.7
Answer:AB≈8.7
Answer:
A.
Step-by-step explanation:
Answer:
The surface area of the second cylinder is equal to 
Step-by-step explanation:
we know that
If two figures are similar then
the ratio of their surfaces areas is equal to the scale factor squared
Let
z-------> the scale factor
x------> the surface area of the smaller cylinder (second cylinder)
y-------> the surface area of the original cylinder (first cylinder)
so

Step 1
Find the scale factor

Step 2
Find the surface area of the second cylinder
we have


substitute and solve for x


150 divided by 25 is 6 so the answer is 6
