Answer:
TSA of cone = πr( l+ r)
slant hieght (l) is 21cm
diameter of base is 14 cm
so radius= 14/2 = 7cm
TSA of cone = 22/7*7 ( 7+21)
= 22*28
= 616 cm²

Answer:
(L) slant height =21cm
diameter =14cm
radius =14/2cm=7cm
Total surface area of cone =22/7*7*(21+7) cm square
=22/7*7*28 cm square
=22*28 cm square
=616 cm square
