Question

give the correct answer....? ​

Answer 1

It is given that Radius of sphere = 3cm

Diameter of spherical ball = 0.6cm

Radius of spherical ball = 0.6/2 = 0.3cm

We know that

Number of balls = Volume of sphere/ Volume of one small ball

So we get,

Number of balls = (4/3 × (22/7) × 33)/ (4/3 × (22/7) × 0.33)

On further calculation,

Number of balls = (4/3 × (22/7) × 27)/ (4/3 × (22/7) × 0.027)

We get Number of balls = 1000

I hope it helps, dude!

Answer 2

$\huge \ \ \ \: Αɳʂɯҽɾ$

Given radius of large sphere = 3 cm

$\bold \ \\ Volume \: of \: Large \: Sphere = \frac{4}{3}\pi \: {r}^{2} = \frac{4}{3} \pi \times {(3)}^{3}$

$\bold \ \ volume = 36\pi \: {cm}^{3}$

Now small spherical balls are to be made from large sphere having radius = 0.3 cm

$\bold \ \ volume \: of \: 1 \: spherical \: ball = \frac{4}{3}\pi {(0.3)}^{3}$

$\bold \ \ volume = 36\pi \: \times {10}^{ - 3} {cm}^{3}$

Now total number of balls are to be made.

$\bold \ \ = \frac{36\pi}{36 \times {10}^{ - 3} } {cm}^{3}$

Hence 1000 balls can be made using larger metallic sphere.
