Answer

You can use following simple idea for it.

-(BOOL) checkMarker:(CLLocation*)locB

{
CLLocation *locA = [[CLLocation alloc]
                    initWithLatitude:24.590095
                    longitude:73.698256];

CLLocationDistance distance = [locA distanceFromLocation:locB];
NSLog(@"%f",distance);

if(distance <= RADIUS)
{
    NSLog(@"You are in Circle ");
    return true;
}
else
{
    NSLog(@"You are not in circle");
    return false;
    }
}
