# A princess hat for a costume is shaped like a cone. The base of the cone is 12 in across and the height is 8 in. The slant height of the outside edge, which is unknown, is the hypotenuse of the right triangle formed with the radius and the height of the cone. (a) Sketch the princess hat. Label the known lengths as described and label the unknown length as x. (b) what is the slant height of the outside edge?plz help!β

Accepted Solution

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]
