V= 4π(3)2
= 4(3.14)(3)2
= 4(3.14)(9)
= 113.04 cubic inches
Therefore, the equation V= 4π(3)2 can be used to find the volume of the sphere.
wrong
Apologies for the mistake. The correct equation to find the volume of a sphere with a diameter of 3 inches is:
V = (4/3)πr³
Given that the diameter is 3 inches, the radius (r) would be half of that, which is 1.5 inches. Therefore, the correct equation is:
V = (4/3)π(1.5)³
Simplifying further:
V = (4/3)π(3.375)
V = 4.5π cubic inches
So, the correct equation is V = 4.5π.
