Answer:
Csa of cone =πrl =22/7 ×14×50= 2200
Sl height = √r sq + h sq = 50= √14+ h
50-14 = h
√36 = h
h=6
Volume = 1/3 π r×r×h
1/3 × 22/7×14×14×6= 1232

Answer:
Radius of base of cone = r = 14 cm
Slant height = l = 50 cm
Curved surface area of cone = πrl
=× 14 × 50
= 22 × 2 × 50
= 2200 cm2
Total surface area of cone = curved surface area of cone + base area of cone
⇒ total surface area = 4400 + πr2
= 4400 +× 14 × 14
= 2200 + 22 × 2 × 14
= 2816 cm2
Therefore, curved surface area is 2200 cm2 and total surface area is 2816 cm2
