We know the formula of blank dia is,
D = π(d^2+4dh)
Where,
Blank dia (D)=? , Cup dia (d)=25mm, height (h)=15mm.
So,
D = π{(25*25)+(4*25*15)}.
D = π(625+1500),
D = 46.09,
D = 46.
D = π(d^2+4dh)
Where,
Blank dia (D)=? , Cup dia (d)=25mm, height (h)=15mm.
So,
D = π{(25*25)+(4*25*15)}.
D = π(625+1500),
D = 46.09,
D = 46.
