Acone has a diameter of 4 cemeteries and a height that is 6 times the diameter using 3.14 for pi which of the following can be used to calculate the volume of the cone

volume of the cone is 11.48 cubic centimeters

Step-by-step explanation:

Assuming we have to find volume of the cone:

We can use volume of cone formula to solve this problem.

Volume of Cone =

Where r is the radius (half of diameter)

h is the height of cone

Given,

diameter is 4 cm, the radius is 4/2 = 2 cm

r = 2

height is 6 times diameter, that is

h = 6 * 4 = 24

h = 24

Now, putting in the values and using 3.14 for , we get volume:

The volume of the cone is 11.48 cubic centimeters

step-by-step explanation:

convert to decimal

answer: 204

step-by-step explanation:

we are told that the revenue is

x⋅(4080−10x)=−10x^2+4080x

this is a quadratic function, so to maximize it we should find the x-value of its vertex. recall that the x-value of the vertex of the parabola ax^2+bx+c is given by the formula −b/2a.

so in this case, we have a=−10 and b=4080, so the x-value of the vertex is

−b/2a= −(4080)/2(−10)=204
