Answer:
A. 219.80 square centimeters
Step-by-step explanation:
The total surface area is given by ...
A = πr(r+s)
where r is the radius and s is the slant height. Filling in the given numbers, you get ...
A = 3.14·(5 cm)·(5 cm +9 cm) = 219.80 cm²
The first thing we must do for this case is to calculate the scale factor.
For this, we make the relationship between two parallel sides.
We have then:

Substituting values we have:

We are now looking for the value of AB
We have then:

Substituting values:

Answer:
The scale factor is:

The value of AB is:

8 over 9
= 8/9
= 8:9
Final answer: 8:9~
