What are the vertices of AA'B'C'if AABC is dilated by a scale factor of 2? A(0, 10)
B(8,6)
C(4, 2)

A. A' (0,20), B' (16, 12), C'(8,4)
B. A'(0,10), B' (16,6), C'(8,2)
C. A'(0, 20), B'(8, 12). C'(4,4)
D. A'(0,5), B (4.3), C (2.1)

the correct option is b

step-by-step explanation:

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a

hello there!

i believe the answer is

(cot2+1)/sec2=cot2

    csc2/sec2=cot2

  (1/sin2)/(1/cos2)=cot2

  (1/sin2)(cos2/1)=cot2

  cos2/sin2=cot2

  (1/tan2)=cot2

  (cot2)=(cot2)

hope this !
