Question

A vessel is in the form of an inverted cone its height is 8cm and the radius of its top which is open is 5cm it is filled with water up to the brim when lead shots each of which is sphere of radius 0.5cm are dropped into the vessel one fourth of the water flows out find the number of lead shots dropped in the vessel

Answer 1

and after that is
volume of N no. of shots=11/21 N cm
volume of lead shot = 1/4 vol. of cone
11/21 N = 1/4 ×4400/21
N = 1100/11
N = 100 Ans

Answer 2

Answer:

Step-by-step explanation:

Radius of cone = 5 cm

Height of cone = 8cm

Volume of cone = 1/3 πr2h

= 1/3 ×22/7 5×5×8

= 1×22×5×5×8/3×7

=4400/21 cm3

1/4 volume of cone =1/4 × 4400/21

=1100/21 cm3

Volume of sphere = 4/3πr3

=4×22×0.5×0.5×0.5/3×7

= 11 /21 cm3

Number of sphere = 1100/21 ×21/11

=100
