Find the circumference and the area of a circle with radius 7 yd . use the value 3.14 for π , and do not round your answers. be sure to include the correct units in your answers?

7x2=14         3.14x14=       43.96 yds

Step-by-step explanation:

probability for j is 1/4

while

a is 1/6

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
