Question

1) A circle of radius 10 is drawn with the origin as centure. a) check wheather each of the points with co-cordinates (6,9), (5,9),(6,8) is inside, outside or on the circle. b)Write the co-cordinates of 8 points on this circle.​

Answer 1

Answer:

Explanation:

i. Distance of the point (5, 9) from the centre of the circle = 25+81−−−−−−√=106−−−√>10

Distance of the point (6, 9) from the centre of the circle = 36+81−−−−−−√=117−−−√>10

Distance of the point (6, 8) from the centre of the circle = 36+64−−−−−−√=100−−−√=10

(5, 9), (6, 9) are outside the circle (6, 8) is on the circle

ii. (10, 0), (0, 10), (–10, 0), (0, –10)

(6, 8), (–6, 8), (6, –8), (–6, –8)
