The formula for the volume of a sphere is V = (4/3) * π * r³. Knowing this, we can plug in the radius:
The sphere's volume is approximately 2144.66 mm^3.
The sphere's volume is approximately 2144.66 mm^3.
Answer:
The turning point of a parabola is the vertex
Vertex form of a quadratic equation:
(where (h, k) is the vertex and a is the coefficient of the variable x²)
Given:
- vertex = (-1, 3)
Therefore, a = 1
Substituting a = 1 and the given vertex into the equation:
Therefore, a = 2 and b = 4
