Cone a and cone b both have a height of 5 in. The volume of cone a is 20.9cubic in, the volume of cone b is 4 times the volume of cone a, about how many times longwr is the diameter of cone b than the diameter of cone a?

two times

Step-by-step explanation:

Given

height of cone A and B  

The volume of cone A  

The volume of cone B is 4 times of cone A

the volume of a cone is  

The volume of cone A

The volume of cone B

divide (i) and (ii) we get

thus, diameter of cone B is twice the diameter of A

what is the your question?

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
