but the answers on the back of the book do not match heres what i did
but the answers on the back of the book do not match heres what i didno. of complete discs = (84*24) / 16pi
but the answers on the back of the book do not match heres what i didno. of complete discs = (84*24) / 16pi= 40
but the answers on the back of the book do not match heres what i didno. of complete discs = (84*24) / 16pi= 40(a) total area of disc cut = 40*16pi
but the answers on the back of the book do not match heres what i didno. of complete discs = (84*24) / 16pi= 40(a) total area of disc cut = 40*16pi(b) area of wasted sheet = (84*24)-(40*16pi)
but the answers on the back of the book do not match heres what i didno. of complete discs = (84*24) / 16pi= 40(a) total area of disc cut = 40*16pi(b) area of wasted sheet = (84*24)-(40*16pi)= 2016 - 2010 = 6
