The Large Hadron Collider at a research lab is contained in a circular tunnel with a circumference of 26.7 km. What is the radius in kilometers of the circular tunnel in terms of π? Enter the correct answer in the box.

[ ]km

4.2494369805536 km

Step-by-step explanation:

r = 4.2494369805536km because 26.7/2π which means:

26.7 ÷ 3.14159265359 x 2 = 4.2494369805536 km.

13.35/π km or 26.7/2π km

Step-by-step explanation:

"In terms of π" means leave pi in the answer. No need to use a decimal equivalent.

The radius is half of the circumference divided by π.

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
