In 5 sentences, explain what you learned regarding circumference and area of a circle. Your answer could involve formulas, vocabulary, the difference between radius and diameter, area of a circle, etc. Please help me.

In order to find the circumference of a circle, you must multiply 2 times pie and the radius. The radius would be half the measure of the diameter. Which would be from the middle point, or the vertex of the circle to the side. The diameter is the measure of the circle from one side to the other. To find the area of a circle, you must multiply pie times radius squared.

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
