Last one and the bottom answer choice is y=(x-4)^2+1 you guys!

If tan2a=cot(a+60), find the value of a, where 2a is an acute angle

The area (a) of a circle with a radius of r is given by the formula and its diameter (d) is given by d=2r. arrange the equations in the correct sequence to rewrite the formula for diameter in terms of the area of the circle.
