This whole problem is only about a circle. Let's not get confused by the rest of the lampshade.
The circumference of any circle is (pi) times (the diameter) .
For this circle, it's (pi) times (13 cm).
They told us what to use for (pi), so it's (3.14) x (13 cm) = <u>40.82 cm</u>
and that's all there is to it.

Answer:
15(2r^2+2r+5)
Step-by-step explanation:
I'm more of a guess and check type of person, but 15 x 2r^2 = 30r^2, 15 x 2r = 30r, and 15 x 5 = 75
