Question

Find the capacity of a conical vessel with height 12 cm and slant height 13 cm.
​

Answer 1

Answer:

314.28cm³ (aprox)

Step-by-step explanation:

Slant height=13cm =>hypotenuse

Height=12cm

Radius=Hyp²-Height²

          =>13²-12²

          =>169-144

          =>25

          = √25=5cm

∴volume of cone=1/3πr²h

          =1/3×22/7×5×5×12

          ≈314.28cm³(aprox)

Answer 2

Answer:

2200/7cm³

Step-by-step explanation:

r²+h²=l²

r²=l²-h²

r²=13²-12²

r²=169-144

r²=25

r=5

1/3πr²h

1/3 x 22/7 x 25 x 12

2200/7 cm³
