Question

4. A metal ball has a radius of 2 inches. What is its volume?

Answer 1

Answer:

Since the volume of sphere is (4/3 pi r³)

there fore the answer will be.

=4/3 *3.142 * (2)³

=4/3*3*3.142*8

=33.51 in².

Answer 2

Given ⤵

➡Radius of metal ball = 2inches.

To find⤵

➡Volume of metal ball.

Solution⤵

⚫Using formula Volume of sphere=4/3πr³

➡Volume of metal ball = 4/3×3.14×2³cu.inch

➡Volume of sphere=12.56/3×8cu.inch

➡Volume of sphere= 100.48/3cu.inch

➡Volume of sphere= 33.49cu.inches(approximate)

✅Hence, the volume of metal ball is 33.49 cu. inches.

✔Extra points⤵

✡Volume of sphere = 4/3πr³

$✡Surface area \: of \: sphere=4\pi {r}^{2}$

Hope this is helpful to you!
