You need to find the volume of the candle holder i’m really confused !

Pythagorean Theorem is a^2+b^2=c^2
2.4^2+b^2=4^2

Is this 7th grade work because ion even work on this & ion even know

Idon't see any graph, however the graph of the function : f(x) = x²-2x+3 is a parabola: 1) open upward (since a> 0)2) it intersects y-axis in 3 (y=3)3) its axis of symmetry is x = +1 ( -b/2a)4) it's minimum is y = -2, so its vertex is (1,-2)5) it doesn't intersect the x-axis since discriminant < 0 

It might be "an artistic taste"  hope i !
