The diameter of a circular glass lens is 8.7 centimeters. paige uses the edge of the lens to trace a circle on a sheet of paper. what is the estimated circumference of the circle?

27.318 centimeters

Step-by-step explanation:

answer: the correct option is d.

explanation:

it is given that the triangle j'k'l' shown on the grid below is a dilation of triangle jkl using the origin as the center of dilation.

from the given graph it is noticed that k(4,8) and k'(2,4). let origin is defined by o and scale factor is defined by k, then

    (1)

distance formula,

put these values in equation (1).

therefore scale factor is     and option d is correct.
