A circle has a radius of 3. An arc in this circle has a central angle of 60°.
What is the length of the arc?
Either enter an exact answer in terms of TT or use 3.14 for it and enter your answer as a decimal.

The full circumference of the circle around all 360° is 2πr where r is the radius. Since r = 3, the full circumference is 2·π·3 = 6π units. 60° is only 60/360 = 1/6 of the way around the circle, so its arc length is 1/6 of the full circumference, or (1/6)·6π = π units.

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
