Question

plz solve the given question. ​

Answer 1

Answer:

3.2 minutes

Step-by-step explanation:

Given:

d = 20 mm

r = 10 mm = 1 cm

h = 10 m/min = 1000 cm/min.

Also given :

D = 40 cm

R = 20 cm

H = 24 cm

Now,

Let conical vessel be filled in x minutes.

=> πr^2h * x = 1/3πR^2H

=> 1000 x = 1/3 * 20 * 20 * 24

=> x = (400 * 8)/1000

=> x = 3200/1000

=> x = 3.2 minutes

Therefore,

The time needed = 3.2 minutes.

Hope it helps!
