HELP PLEASE 13. Triangle ABC is dilated by a scale factor of 3. The
vertices of ABC are A(1,5), B(2,3) and C(4,2). What are
the vertices of Triangle A'B'C'.
A. A'(3,15), B'(6,9), C'(12,6)
B. A'(1,15), B'(2,9), C'(4,6)
C. A'(3,5), B’(6,3), C'(12,2)
D. A'(1/3, 5/3), B'(2/3,1), C'(4/3, 2/3)

the answer is:

the correct option is the option b.

to calculate the surface area of the right cylinder, we need to use the following formula:

from the picture we know that:

so, substituting and calculting we have:

hence, we have that the correct option is the option b.

have a nice day!

multiply each one by 3.14
