Acylinder has a volume of 140 cubic meters and a height of 14 meters. what is the area of the base?

10 square meters

Step-by-step explanation:

We know that the volume of cylinder is given by :-

, where r is radius and h is height of cylinder.

Now, according to the question we have :

Also, the area of base is given by :-

Therefore, the area of the base =10 square meters

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
