Sample WAEC WASSCE Mathematics 2007 questions
1. Find the circumference of a circle of radius 7 cm. Take pi = 22/7.
- 44 cm
- 22 cm
- 154 cm
- 49 cm
Answer: A. 44 cm
The circumference is 2*pi*r = 2*(22/7)*7 = 44 cm.
2. Two angles of a triangle are 48 degrees and 67 degrees. What is the third angle?
- 55 degrees
- 65 degrees
- 75 degrees
- 115 degrees
Answer: B. 65 degrees
Angles in a triangle sum to 180 degrees, so the third angle is 180 - 48 - 67 = 65 degrees.
3. A trapezium has parallel sides of lengths 8 cm and 14 cm and a perpendicular height of 5 cm. Find its area.
- 50 cm^2
- 45 cm^2
- 55 cm^2
- 110 cm^2
Answer: C. 55 cm^2
Its area is half the sum of the parallel sides times the height: (8 + 14)*5/2 = 55 cm^2.
4. A right-angled triangle has shorter sides of 9 cm and 12 cm. Find the length of its hypotenuse.
- 12 cm
- 18 cm
- 13 cm
- 15 cm
Answer: D. 15 cm
By Pythagoras' theorem, the hypotenuse is sqrt(9^2 + 12^2) = sqrt(225) = 15 cm.
5. An angle at the circumference subtended by an arc is 35 degrees. What is the angle at the centre subtended by the same arc?
- 70 degrees
- 35 degrees
- 105 degrees
- 140 degrees
Answer: A. 70 degrees
The angle at the centre is twice the angle at the circumference, giving 2*35 = 70 degrees.
