Answer:


Step-by-step explanation:


Diameter of cylindrical jar = 14cm

Radius of cylindrical jar, R = 7cm

Rise in water level after

dropping lead shots ,H = 2.8cm

Let the radius of each leadshot be r

A.T.Q. :


Volume of = Volume of rise in

300 leadshots. water level


= 300×(4/3×π×r^3)= π×R^2×H


= 100 ×4×πr^3 = π×(7)^2×2.8


= r^3 =π×(7)^2×28

/π×400×10

After solving

= r^3. = 7^3

/10^3

= r = 0.7cm


Diameter of each leadshot = 0.7×2

= 1.4cm

(Ans.)
