Does anybody know how to do this

   =20.724 inches

Step-by-step explanation:

The circumference of a circle can by found by using

C = pi *d  where d is the diameter and pi can be approximated by 3.14

C = 3.14 * (6.6)

   =20.724 inches

yes

Step-by-step explanation:

do you want help? I. am willing to!!

i used to know how to do this in 7th but i forget easily

step-by-step explanation:

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
