The shot used in men’s shot put has a volume of about 905 cubic centimeters.


With V = (4/3) pi r^3

i need help to find the radius of the shot with the formula.

is the shape supposed to be a cylinder ?

No the shape is spherical like a cannonball but ou do not need to know that because they give you the volume:

V = (4/3) pi r^3 = 905
so
r = cube root of [ 3*905 / (4 pi) ]
= [ 3*905 / (4 pi) ] ^(.333333....)
about 6 cm :)
Thank you, and i just realized what a shot put was, i was thinking this was like a syringe.
