Answer:
[tex]V=1437.33\ \text{unit}^3[/tex]
Step-by-step explanation:
We need to find the volume of a sphere when the radius is 7. To find volume we must know the formula used to find the volume of a sphere. The formula of volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}\times \dfrac{22}{7}\times (7)^3\\\\V=1437.33\ \text{unit}^3[/tex]
So, the volume of a sphere when the radius is 7 is [tex]1437.33\ \text{unit}^3[/tex].
