Question

find the capacity in litres of a conical vessel with radius 7cm, slant height 25 cm.

Answer 1

Hiii friend,


Radius of conical vessel (R) = 7 cm

Slant Height (L) = 25 cm

(L)² = (H)² + (R)²

(H)² = (L)² - (R)² = (25)² - (7)² = 625 - 49 = 576 cm


H = ✓576 = 24 cm


Therefore,


Capacity of vessel = 1/3 πR²H = 1/3 × 22/7 × 7 × 7 × 24 = 1/3 × 22 × 7 × 24 = 3696/3 = 1232 m³.
