in question 2 b ii] we shall first find the perimeter of the arc

1--- 90\360 *2*8*pie
this equals to 4 pie cm
2---- nextly we should subtract the 2 radii since we just want the perimeter of the shaded segment this equals to 4 pie---16 cm3---- lastly we shall add the length of AD since we are finding the perimeter and in the first step we only got the perimeter of the curved surface4-- lastly combine all values4 pie-16cm+(square root of 128 )=7.88079113 cm to 3.s.f this equals to 7.88 cm
