Volume of cylinder = Let the radius of the base of cone be R cm. then ... A cylinder with base radius 8 cm and height 2cm is melted to form a cone of height 6 cm.
Radius of cone = ?
Height of cylinder = 2 cm
Height of cone = 6 cm
Volume of cylinder = Volume of cone
πr² h = 1/3 πr² h
22/7 × 8 × 8 × 2 = 1/3 × 22/7 × r² × 6
8 × 8 × 2 × 3 / 6 = r²
8 × 8 = r²
r = √8 × 8
r = 8 cm
Radius of cone = 8 cm
