Question

plz . solve it fast .....

Answer 1

We know that  
No. of lead shots dropped in the vessel= Volume of water flown out/ Volume of one lead shot


Now, The volume of water flown out= 1/4 volume of cone (Given)

So, Volume of water flown out= 1/4 * 1/3 * pi * r² * h
= 1/4 * 1/3 * 22/7 * 5 * 5 * 8
= 1100/ 21 cubic cm


Volume of 1 lead shot= Volume of sphere
= 4/3 * pi * r³
= 4/3 * 22/7 * (0.5)³
=11/21 cubic cm


So, No. of lead shots= (1100/21) / (11/21)
= 1100/ 21 * 21/ 11
=100


Answer= 100 lead shots

Answer 2

hey dear


here is your answer


given



as you know the vessel of inverted cone


it's cone height is 8cm

radius = 5cm


sphere lead shot

it's radius is 0.5cm


1/4 water flows out


so we use the formula of cone


1/4* 1/3 pi r square h


1*4 * 1/3 *22/7 * 5 *5 * 8


so we simplify this

1100/21


Volume of one lead shot = volume of sphere


4/3 pi r cube

4/3 * 22/7* 0.5*0.5*0.5

so we simplify this

and it comes

11/21

so no of lead shot

(1100/21) / (11/21) ( 11/21 it become 21/11 reciprocal using dividing rule)

So

1100/21 / 21/11

so we simplify this

it comes 100



So answer is 100 lead shot s


hope it helps

thank you
