NECO Mathematics Question and Answers
No 4(i)
length of Arc of the sector
Titter= 72?, r = 14cm
L= titter / 360 x 2 pie r
==> L= 72/360 x 2 x 22/7 x 14
=44352/2520 = 17.6cm
(ii) perimeter of the sector
Perimeter = titter/360 x 2 pie r + 2r = 17.6 +(2×14) =17.6+28= 45.6cm
(iii) Area of the sector
Area = Titter/360 x pie r? =
72/360 x 22/7 x (14)? = 72 x 22 x 196/2520
Area= 310464/2520 = 123.2cm?

X=a+by—-(1)
When y=5 and x= 19
19=a+5b—(11)
When y=10 and x=34
34=a+10b—-(iii)
Solving equ(ii) and equ (iii)
Simultaneously
Equ(iii)– equ(ii)
A+10b=34
A+5b = 19/5b=16
B=15/5=3
Putting b=3 in equ(ii)
19=9+5(3)
19=9+15
9=19-15
9=4
8i
Putting a=4 and b=3
In equ(I)
X=4+3y—
This is the relationship between x and y
(Ii)
When y= 7
X=4+3(7)
X=4+21
X=25
