Find the circumference of this. Radius= 2.5 centimeters. Round to the nearest hundredth

Circumference of a cicle in terms of radius:

Circumference = 2·π·r = 2·3.14·2.5 = 15.7(*)

In terms of diameter:

Circumference = π·d = 3.14·5 = 15.7(*)

In terms of area:

Circumference C = √4·π·A = √4·π·19.63 = 15.7(*)

Answer?→(*) 15.71

Note: for simplicity, the operations above were rounded to 2 decimal places and π was rounded to 3.14.

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
