Answer:
(i) The Slant Height of cone in 10 cm .
(ii) The TSA of cone is 301.44 cm .
Step-by-step explanation:
(i) Fist assume the half part of cone as triangle then
Height - 8 cm
Base - 6 cm
slant height - x
(x)^2 = (8)^2 + (6)^2
x^2= 64 + 36
x^2 = 100
x = √100
x= 10 cm
(ii) TSA of cone is πr(l+r)
=22/7 × 6(10+6)
= 22/7 × 6 × 16
= 22/7 × 96
= 3.14 × 96
= 301.=44 cm
