## Why pressure will act on centroid

Asked by anirbanbag81 25th November 2017 9:13 AM

## 29)find the centroid of the circle whose vertices are (4,-8),(-9,7),(8,13).   30)if the area of triangle PQR,where P(2,1),Q(x,1) and R(2,y) is 6 sq units ,then find the relationship between x and y.   31)the centre of a circle is (x+2,x-1) .Find x if the circle passes through (2,-2) and(8,-2).   32)if P(9a-2,-b) divides the line segment joining A(3a+1,-3) and B(8a,5) in the ratio 3:1 . Find the value of a and b.

## the circle x2+ y2= a2 is inscribed An equilateral triangle with the vertex at (a, 0)The equation of the side opposite to this vertex is (A) 2x–a = 0 (B) x + a = 0 (C )2x + a = 0 D) 3x–2a = 0
