Question

a shot put is a metallic sphere of radius 4.9 Cm . If the density of the metal is 7.8g per cm3 ,find the mass of the shot put​

Answer 1

Step-by-step explanation:

Volume of a Sphere= 4/3 πr^3

Density = Mass/ Volume

d=m/v

d= 3m/4πr³

m= d/3×4πr³

m= 7.8/3×4×3.14×4.9×4.9×4.9

m= 2.6×4×3.14×4.9×4.9×4.9

m=3841.94574

m=3841.95 gm
