Answer 2

Answer:No. of solid spheres=$\large\boxed{5}$

Step-by-step explanation:

Let n be no. of solid spheres

Volume of n solid spheres = Volume of solid metal(cylindrical metal)

$n(\frac{4}{3}\pi(r^{3}))=\pi(R^{2})(h)$

r=3cm and R=2cm and h=45cm

$n(\frac{4}{3}\pi(3^{3}))=\pi(4)^{2}(45)$

$n(\frac{4}{3}\pi(27))=\pi(4)(45)$

$n=5$

$No. of solid spheres=\large\boxed{5}$
