Answer:
113.1 m³
Step-by-step explanation:
In terms of diameter, the volume of a sphere is given by the formula ...
V = (π/6)d³
For a diameter of 6 m, the volume is ...
V = (π/6)(6 m)³ = 36π m³ ≈ 113.1 m³
The volume of the sphere is about 113.1 cubic meters.
(2t-4)(3t+3)
2t(3t+3)-4(3t+3)
6t^2+6t-12t-12
6t^2-6t-12
