\(d^2*π*h/4\) = 3,5002 * \(π\) *5505 /4= 15132659.11 considering u need the volume then u should round the answer to 4 s.f which will be around 15130000 mm3 . Now if u want the answer in either cm3 or m3 then just use the basic S.I units to convert the answer.
Next problem
15130000 mm3 = 15130 cm3
Density = \(\rho=m/V\)
= \(\rho= 414/15130\)
= \(\rho= 0.027 gcm^-3 \) or \(27.36 kgm^-3 \)
For the first problem I divided the equation by 4 cuz i dont know if only the h is being divided by 4 or the whole equation.
If only the h is being divided by 4 then all the answers will be changed.
