In the diagram below, what is the approximate length of the minor arc AB?

D. 31.4cm

Step-by-step explanation:

To know the measure of the arc AB, we must first know the measure of the perimeter (the circumference) of the circle:

where is a constant,

and is the radius which is the line that goes from the center of the circle to a point on the circumference, in this case:

so the measurement of the circumference is:

Now, we don't want the measurement of the entire circumference, we only want 60 ° of the total 360 ° degrees of the circle. For this we must divide the measure that we find for the circumference by 360 and multiply the result by 60:

which is option D

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
