A circle at the origin whose is 2 units is 2 is inscribed in a right triangle whose base is 8 units and altitude 6 units. Find

Question

a) The equation of the circle
b)The area and circumference of the circle
c)The area of the right triangle exluding the area covered by the circle

Answer 1

(a) x^2+y^2 = 4
