Radius and Centre of Circle

Hi,
I am drawing a circle using ellipse because there is no explicit command for this.

Code:

---

        pDC->Ellipse(CRect(70, 170, 300, 400));

---

Kindly tell me what is the centre of circle and what is radius in the above command?

Zulfi.

The length of the radius is half the size of one of the sides of the square. The given CRect is a square of length 230 so the radius of the circle is 115.

The centre of the circle is the centre of the bounding CRect which is (70 + 115, 170 + 115) or (185, 285).

Thanks for your useful guidance.

Zulfi.
