This is correct.
The diameter of the semicircle starts from the centre of the quarter circle and ends at the circumference of it.
So this diameter is equal to the radius of the quarter circle, which is 30 cm.
The distance from the centre to any point of the circumference is always the same (radius doesn't change)
