lets consider a point in ellipse say (0,2) which satisfies the ellipse equation.then according to distance formula u can calculate the radius of th ecircle as root5 then 3r^2 will be equal to 15 so ur ans is 15
archanapamp:
see the point (0,2) satisfies the ellipse equation x^2+4y^2=16 and this point(0.@) is common to both circle and ellipse so this point lies on the circle and according to distance formula u can calculate the radius
(1,15^0.5/2) also satisfy circle and ellipse
confused?
BY the answer is 11/
ok its better to see mandankapoors ans it is more logical
but its 11.25
the answer is just 11
mayb some calculation mistake repeat the process and calculate again
ok
lopa the ans is 11.25 even i have calculated it mayb the ans given is rounded up
