Question

find C. S. A &T.S.S of a cone of r=17cm and slant height is 20cm.​

Answer 1

Answer:

CSA of cone =  106.86 sq.cm

TSA of cone =   1976.86 sq.cm

Step-by-step explanation:

CSA of cone = πrl sq.units

                      = 22/7 * 17 * 20 sq..cm

                      = 374/7 * 20 sq.cm

                      =  748/7 sq.cm

                      =  106.857 sq.cm

                      =   106.86 sq.cm ( Round off )

TSA of cone   =   πr ( l+r ) sq.units

                       =  22/7 * 17 ( 20 + 17) sq.cm

                       =  22/7 * 17 * 37 sq.cm

                       =   374/7 *37 sq.cm

                       =   13838/7 sq.cm

                       =    1976.857 sq.cm

                       =   1976.86 sq.cm (Round off)
