Question

calculate the volume of solid cone of base radius 3 cm and perpendicular height 7 cm

Answer 1

Answer:

22×3×3×7÷(7×3)

22×3

66 sq cm

Answer 2

Answer:

2574cm³

Step-by-step explanation:volume of cone =13π(base)²height

Base radius=3 cm

Height=7cm

Volume=13×22/7×3×3×7

             =13×22×3×3

             =2574cm³
