       Let’s Practice!

       Find answers the following questions  on paper then upload your answer

       via the following link: https://forms.gle/yVoSSmcj2eXgMAx19

       1.  A cone birthday hat with 12 cm of diameter and 15 cm of slant height
           made  from  paperboard.  If  cost  of  a  sheet  paperboard

           size 30  cm  x  40  cm is  Rp.  1,500,  -  how much  the low cost  to  make  2
           dozen cone hats?


       2.  The surface area of the cone is 364 cm  and the radius is 7 cm. Find
                                                           2
           the slant height of cone!

                                                      3
       3.  The  volume  of  a  cone  is  1.256  cm .  If  the  hight  of  cone  is  12  cm,
           calculate the radius of cone base!

       4.  A conical tumpeng rice with 14 cm of diameter and 30 cm of  height.

           Calculate  how  many  kilograms  of  rice  are  needed  to  make  one
                                   3
           tumpeng rice! (1 cm  = 0,9 gram)
                                                                                3
       5.  A cone is inserted right into a cylinder which has 7.850 cm  of volume
           so  the  diameter  of  cone  is  equal  to  the  diameter  of  cylinder.  If  the

           cylinder radius is 10 cm, calculate:
           a) cone volume

           b) the slant height.
