Question

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 ?

Answer 1

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....)

Answer 2

about 6 cm :)

Answer 3

Thank you, and i just realized what a shot put was, i was thinking this was like a syringe.
