Mathematics Question on Circle
The circle x2+y2+4x−7y+12=0 cuts an intercept on y -axis of length
Answer
Explanation:
Given:Equation of a circle, x2+y2+4x−7y+12=0We have to find the y -intercept made by the circle.Intercept on y -axis made by a circle x2+y2+2gx+2fy+c=0 is 2(f2−c)We have equation of the given circle, x2+y2+4x−7y+12=0Thus required intercept=2(−72)2−12=2(494−12)=1Hence, the answer is 1.00.
