Found the centre of the circle, the radius and a point. It now asks for the area of the rectangle in which this circle is enclosed, no idea what to do!

So the smallest rectangle that will enclose the circle has length equal to the diameter and width equal to the diameter. The area of a rectangle is length by width, thus the area of the rectangle is diameter by diameter which equals diameter(squared) Remember diameter is two times the radius

a square will perfectly enclose a circle. so the radius of the circle will be half the height (or width!) of the square. just find the area of the square!
