Question

a vessel is in the form of an inverted cone its height is 11 cm and the radius of its top which is open is 2.5 cm It is filled with water up to the Rim when lead shots
each of which is spear of radius 0.25 CM are dropped Into The vessel 2/5of water flows out find the number of lead shots dropped Into The vessel ​

Answer 1

Answer:480 lead shots

Step-by-step explanation:

R=2.5

H=11

r=0.25

Volume of lead shots=Vol of water lost

Volume of water lost =2/5Volume of water in cone

•Volume of water lost=2/5(1/3×22/7×R^2×H)

= 28.809

Vol of 1 lead shot=4/3×22/7×r^3

=0.065

•No of cones=Vol.of water lost/Vol.of

1 lead shot

=28.809/0.065

=480
