Question

What is the volume of this sphere?

Use a = 3.14 and round your answer to the nearest hundredth.
2 in

Answer 1

33.49 cubic inches

Explanation:

the volume of a sphere is represented by (4/3)pi(r)^3

pi is 3.14 and r is 2

so 4/3(3.14)(2^3)

2^3 is also 8

4/3(3.14)(8)

the final answer is 33.4933333

OR when rounded it is 33.49

Answer 2

Statement:

The radius of the sphere is 2 inches.

To find out:

The volume of the sphere.

Solution:

• Radius (r) = 2 in
• π we have to consider as 3.14.
• We know, volume of a sphere
  `= (4)/(3) \pi \: {r}^(3)`
• Therefore, the volume of the sphere

`= (4)/(3) * 3.14 * {(2)}^(3) \: \: cubic \: \: inches \\ = (4)/(3) * 3.14 * 8 \: \: cubic \: \: inches \\ = 33.49 \: \: cubic \: \: inches`

Answer:

The volume of the sphere is 33.49 cubic inches.
