Answer:

s = 10

Step-by-step explanation:

As the triangles are similar,

The sides are proportional too.

So, we can see that

Side AB is proportional to XY

So, XY side is half of AB.

So, BC will be 5×2 = 10

So, 10 is the correct answer.

Answer:

452.39

Step-by-step explanation:

to find the surface area of a sphere all you need is the radius (half the diameter) and assuming the sphere touches both top and bottom that makes the radius 6 so your equation is

SA=4πr^2

SA=4*π*6^2

SA=4*π*36

SA=4*113.09

SA=452.389

then rounded up to 452.39, that is your answer
