If a circle of radius 2 rolls along the x-axis in quadrants i and ii, what is an equation for the path of the center of the circle?.

it could be 1,3 and more others to create a cylinder.

step-by-step explanation:

step-by-step explanation:

this can be solved first with pythagorean theorem, which tells us to square both legs of the triangle and sum it. this will be equal to the square of the hypotenuse.

the hypotenuse is the side "opposite" the 90 degree angle, which is x.

so we can write using pythagorean theorem,

simplifying:

to further simplify this radical, we need to use the property  

thus
