Question

Hurry and answer this please. Find the volume of the sphere use 3.14 for pi

Answer 1

44.6cm³

Explanation:

V=3/4×3.14×2.2³=44.6cm³

Answer 2

Option 2) 44.6 cm³ os the correct answer.

Step-by-step explanation:

SOLUTION :

Here we have given that the radius of the sphere is 2.2 cm. We have to find the volume of sphere.

Finding the volume of sphere by substituting all the given values in the formula :

`\quad{\longrightarrow{\sf{V_((Sphere)) = (4)/(3)\pi{r}^(3)}}}`

• V = volume
• π = 3.14
• r = radius

`\quad{\longrightarrow{\sf{V_((Sphere)) = (4)/(3)\pi{r}^(3)}}}`

`\quad{\longrightarrow{\sf{V_((Sphere)) = (4)/(3) * 3.14 * {(2.2)}^(3)}}}`

`\quad{\longrightarrow{\sf{V_((Sphere)) = (4)/(3) * 3.14 * 10.65}}}`

`\quad{\longrightarrow{\sf{V_((Sphere)) = \frac{4}{\cancel{3}} * 3.14 * \cancel{10.65}}}}`

`\quad{\longrightarrow{\sf{V_((Sphere)) = 4 * 3.14 * 3.55}}}`

`\quad{\longrightarrow{\sf{V_((Sphere)) = 12.56 * 3.55}}}`

`\quad{\longrightarrow{\sf{V_((Sphere)) = 44.58 \: {cm}^(3)}}}`

`\quad{\longrightarrow{\sf{\underline{\underline{\pink{V_((Sphere)) \approx 44.6 \: {cm}^(3)}}}}}}`

Hence, the volume of sphere is 44.6 cm³.
