Question

the diameter of spherical iron ball is 14 cm if one cm cube of iron weight 7.8 GM what is the weight of iron ball​

Answer 1

...we calculate the volume of the ball sphere:

(4ft²)/3 = (4*ft*7^3)/3 = (1372ft)/3(cm^3)about 1436.026667cm^3=1436cm^3

(ft=3.14)

calculate the weight:

1cm^3 weighs 7.8gm

1436cm^3 weigh 1436*7.8≈11200.8gm≈11,200kg
