Question

Toy rubber balls are packaged in a cylinder that holds 3 balls.

The diameter of each ball is 6.3 cm. Find the volume of the
cylinder. Use 3.14 for π

Answer 1

Answer: V= 31.15665

Step-by-step explanation:

diameter divided by 2 to give 3.15 then multiply by 3.15

then squared

Answer 2

392.58 cubic centimeters.

Explanation:

The formula for the volume of a sphere is:

`\boxed{\bold{V = (4)/(3)* \pi* r^3}}`

Given that the diameter of each ball is 6.3 cm, we can find the radius (r) by dividing the diameter by 2:

`\bold{r = (6.3 cm)/(2) = 3.15 cm}`

Now we can calculate the volume of one ball:

`V_(ball )= (4)/(3)* 3.14 * (3.15 cm)^3=130.86 cm^3`

We multiply the volume of one ball by 3 to find the total volume occupied by three balls,

`V_(total) = 3 * V_(ball)`

Calculating the values:

`V_(ball) = 3*130.86 cm^3=392.58 cm^3`

Therefore, the volume of the cylinder that holds the three rubber balls is approximately 392.58 cubic centimeters.
