I dont know how to write the equation.
You have two circular flower beds, as shown. The sum of the areas of the two flower beds is 136π square feet. Find the radius of each bed.
Big flower bed = r ft Small flower bed = (r-4) fy
find the diameter
the locus of the point of intersection of perpendicular tangents drawn to each of circles x2 + y2 = 16 and x2 + y2 = 9 is a circle whose diameter is (I)5 (ii)√7 (iii)2√7 (iv)10
angle between tangents
if two tangents are drawn from a point on x2 + y2 = 16 to the circle x2 + y2 = 8 then the angle between the tangents is (I)900 (ii)450 (iii)1200 (iv)1800
find the locus
locus of point of intersection of perpendicular tangents drawn one to each of the circles x2 + y2 = 8 and x2 + y2 =12 is (I) x2 + y2 = 4 (ii)x2 + y2 = 20 (iii)x2 + y2 = 208 (iv)x2 + y2 = 16
