Asphere is cut into 8 congruent pieces. The radius of the sphere is 8 centimeters. One piece is shown in the
diagram
What is the surface area of one piece of the sphere, as
shown in the diagram? Express the answer in terms of
8 cm
O 647 cm
O 80x cm
256.7 cm
O 3847 cm
8 cm
8 cm

i think it is 100.53125 !! hope i helped :)

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
