A:
Answer:Part a) The drawn in the attached figurePart b)The slant height of the outside edge is [tex]x=10\ in[/tex] Step-by-step explanation:Part a) The drawn in the attached figurePart b) What is the slant height of the outside edge? we have thatThe diameter of the base of the cone is 12 inso[tex]r=12/2=6\ in[/tex] ----> the radius is half the diameter[tex]h=8\ in[/tex] Applying the Pythagoras Theorem find the slant height x[tex]x^{2}=r^{2}+h^{2}[/tex]substitute the values[tex]x^{2}=6^{2}+8^{2}[/tex][tex]x^{2}=100[/tex][tex]x=10\ in[/tex]
