Find tha volume of cone
Find the capacity in liters of a conical vessel with radius 7cm slant height 25cm
Given, Radius (r) = 7 cm
Slant height (l) = 25 cm
Let h be the height of the conical vessel.
Slant height (l)²= r²+h²
So, h = √(l² – r²)
h = √(25²– 7²) = √(625- 49)
h = √576
h = 24 cm
Volume of the cone = 1/3 πr²h
= (1/3 × 22/7 × 7 × 7 × 24)
= 1232 cm³
[1 cm³= 1/1000 L]
Hence, Capacity of the vessel = (1232/1000) L= 1.232 L
