Answer:
538.57 m³
Explanation:
The formula to find the volume of a sphere is:
V = 4 π r³
Given that,
diameter ⇒ 7 m
∴ radius = d / 2
radius ( r ) = 7 / 2 = 3.5 m
Let us find the volume now.
V = 4 π r³
V = 4 π × ( 3.5 )³
V = 4 π × ( 3.5 )³
V = 4 π × 42.875
V = 4 π × 42.88
V = 12.56 × 42.88
V = 538.57 m³
