Answer:
The answer is...
Step-by-step explanation:
Purplea
Answer:
Base radius:
Step-by-step explanation:
Considering the cone is Right Circular Cone:
Volume of the cone =
Given :
Putting in the formula:
Multiply by '3' both sides:
Divide by '25.12' both sides:
So, the cone has base radius:
Answer:
The vertex is ( -2, -4)
Step-by-step explanation:
The vertex form is
y = a( x-h) ^2 +k
where ( h,k) is the vertex
f(x) = (x + 2)^2 – 4
Rewriting
f(x) = (x - -2)^2 – 4
The vertex is ( -2, -4)
