Sample NECO SSCE Mathematics 2022 questions
1. Three angles of a quadrilateral are 85 degrees, 102 degrees and 91 degrees; what is the fourth angle?
- 82 degrees
- 78 degrees
- 92 degrees
- 98 degrees
Answer: A. 82 degrees
The angles of a quadrilateral sum to 360 degrees, so the fourth angle is 360 - 85 - 102 - 91 = 82 degrees.
2. Find the circumference of a circle of radius 7 cm, taking pi as 22/7.
- 22 cm
- 44 cm
- 49 cm
- 154 cm
Answer: B. 44 cm
The circumference is 2*pi*r = 2*(22/7)*7 = 44 cm.
3. A triangle has base 12 cm and perpendicular height 9 cm; what is its area?
- 21 cm^2
- 48 cm^2
- 54 cm^2
- 108 cm^2
Answer: C. 54 cm^2
The area is half the product of base and height, giving (12*9)/2 = 54 cm^2.
4. A cylinder has radius 3 cm and height 10 cm; what is its volume, taking pi as 3.14?
- 94.2 cm^3
- 188.4 cm^3
- 300 cm^3
- 282.6 cm^3
Answer: D. 282.6 cm^3
The cylinder's volume is pi*r^2*h = 3.14*9*10 = 282.6 cm^3.
5. The bearing of point P from point O is 065 degrees; what is the bearing of O from P?
- 245 degrees
- 155 degrees
- 295 degrees
- 335 degrees
Answer: A. 245 degrees
The reverse bearing is found by adding 180 degrees, so 065 + 180 = 245 degrees.
