Determine the similarity transformations that verify △ABC ~ △A''B''C'. The first transformation mapping △ABC to △A'B'C' is a . The second transformation mapping △A'B'C' to △A''B''C' is a .

is this a multiple choice question?

if so it's a and c

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

answer: 1+1

step-by-step explanation: 1+1 is at least 2

answer: 4  

the square root of 16 is 4. it is a very simple mathematic concept. a square root when a number multiplied by itself will result in a number. here, the number 16 comes when 4 is multiplied by 4. hence the square root of 16 is 4. you can always figure out a square root by the inverse operation of squaring.
