Answer:
<em><u>1</u></em><em><u>.</u></em><em><u> </u></em><em><u>A cross section is the new face you see when you slice through a three-dimensional figure. For example, if you slice a rectangular pyramid parallel to the base, you get a smaller rectangle as the cross section.</u></em>
11+11+4+4=30 so the answer is thirty
The answer should be 9 rounded because 2 pi r 56.5 will give u that.
360°/60 = 6
25 x 6 = 150°
18 x 6 = 108°
15 x 6 = 90°
2 x 6 = 12°
then draw a pi chart with these angles
hope this helps! please mark branliest?
