Question

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

Answer 1

Step-by-step explanation:

Life is a characteristic that distinguishes physical entities that have biological processes, such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased (they have died), or because they never had such functions and are classified as inanimate.

Answer 2

Answer:

Given ⤵

➡Radius of metal ball = 2inches.

To find⤵

➡Volume of metal ball.

Solution⤵

$⚫Using \: formula \: Volume \: of \: sphere = \frac{4}{3} \pi {r}^{3} \\ where \: r = radius \: of \: sphere$

⚫Putting the value of π=3.14.

$➡Volume \: of \: metal \: ball = \frac{4}{3} \times 3.14 \times {2}^{3} cu.inch \\ ➡Volume \: of \: metal \: ball = \frac{12.56}{3} \times 8cu.inch \\ ➡Volume \: of \: metal \: ball = \frac{100.48}{3} cu.inch \\ ➡Volume \: of \: metal \: ball = 33.49cu.inch(approximetly)$

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

✔Extra points⤵

$✡Volume \: of \: sphere = \frac{4}{3} \pi {r}^{3}$

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

Where r= radius of sphere.
