⚫ HEIGHT OF CONE = 48 cm
⚫ BASE AREA = 616 cm²
πr² = 616 cm²
22/7 × r² = 616
r² = 616×7/22
r² = 196
r = √196
r = 14 cm ...
============================================
LAS of cone
l = √h²+r²
l = √(48)²+(14)²
l = √2304 + 196
l = √2500
LSA = 50
==============================================
TSA of cone = πr(r + l )
22/7 × 14 (14 + 50 )
44 × 64
TSA of cone is = 2816 cm²

Step-by-step explanation:
HEIGHT OF CONE = 48 cm
⚫ BASE AREA = 616 cm²
πr² = 616 cm²
22/7 × r² = 616
r² = 616×7/22
r² = 196
r = √196
r = 14 cm ...
LAS of cone
l = √h²+r²
l = √(48)²+(14)²
l = √2304 + 196
l = √2500
LSA = 50
TSA of cone = πr(r + l )
22/7 × 14 (14 + 50 )
44 × 64
TSA of cone is = 2816 cm²
