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
