Kayla says that the point labeled C in the diagram below is the center. Raymond says that point C is the radius. Who is correct and why? Kayla is correct; the center is a fixed point in the middle of the sphere. Kayla is correct; the center is a line segment from the center to the surface of the sphere. Raymond is correct; the radius is the fixed point in the middle of the sphere. Raymond is correct; the radius is a chord that is from the center to the surface of the sphere.

5/12, or 5: 12

step-by-step explanation:

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl
