declaring Arrays in .m file

Sphere *ball = [[Sphere alloc] init];

    ball.radius = 34;

    NSLog(@"\nball radius %f\n", ball.radius);

ok so we've created an instance of sphere called "ball" and set and logged its the Radius property. how to we set and log the center (which is an array)? I guessed something like— ball.center = {23, 32, 45};

—but that didn't work. help! :)

here are the two properties and the method.

@property (nonatomic) float radius; @property (nonatomic, strong) NSArray *center;

-(void)setCenter:(NSArray *)center radius:(float)radius;

it's not from a challenge, it is from a video: http://teamtreehouse.com/library/objectivec-basics/introduction-to-objectivec/introducing-property

it ends without declaring and logging the array that is the "center" property. we set ball.radius = 34... but how do we set ball.center (which should have 3 floats)?
