Answer:

r=2.9cm

Step-by-step explanation:

we know the formula, mass= density*volume

as a result we can figure out the volume = mass/density

=485/8 cm^3

=60.625cm^3

here comes another formula of volume of cone = \frac{1}{3}\pir^{2}h^{}

we will use this to find the radius,

\frac{1}{3}\pir^{2}h^{}=60.625

\pir^{2}h^{}=181.875

h is 70mm which we will turn to 7cm

\pir^{2}*7=181.875

r^{2}=8.27

r=2.875825cm

r=2.9cm

nice question. hope this helps
