What is the volume of a sphere with a radius of 1 m?

To determine the volume of a sphere, the formula used is ( V = \frac{4}{3} \pi r^3 ), where ( r ) is the radius of the sphere. In this scenario, the radius is given as 1 meter.

Substituting the value into the formula, we calculate:

1. First, find ( r^3 ):

[

1^3 = 1

]

2. Then, multiply by ( \pi ):

[

V = \frac{4}{3} \pi \times 1 = \frac{4}{3} \pi

]

3. The value of ( \pi ) is approximately 3.14, so:

[

V \approx \frac{4}{3} \times 3.14 \approx \frac{12.56}{3} \approx 4.19

]

Thus, the volume of a sphere with a radius of 1 meter is approximately 4.19 cubic meters. Therefore, the choice reflecting this correct volume calculation aligns with option D.

This highlights how important it is to apply the formula
