(1) radius 6 cm, height 7 cm
Find the capacity in litres of a conical vessel with
(1) radius 7 cm, slant height 25 cm (ii) height 12 cm, slant height 13 cm
10 m] find the radius of the​

Answer 1

Answer:

hello here your answer

in this question put the formula of l2= h2+r2

Answer 2

Step-by-step explanation:

(ii) Given: Height (h) = 12 cm

Slant height (l) = 13 cm

Let r be the radius of the conical vessel.

Slant height (l)²= r²+h²

r = √ r² - h²

r = √13²– 12²

= √169 – 144

r = √25

r = 5 cm

Volume of the cone = 1/3 πr²h

= (1/3 × 22/7 × 5 × 5 × 12)

= (2200/7) cm³

Capacity of the vessel = (2200/7× 1000) L

= 11/35 L

Capacity of the vessel =11/35 L
