Key Topics Covered in WAEC Math Core 2014 and Their Answers
Algebra and Number Patterns
Question Example:
Simplify: \( \frac{2x^2 - 8}{4x} \)
Solution:
\[
\frac{2x^2 - 8}{4x} = \frac{2(x^2 - 4)}{4x} = \frac{2(x - 2)(x + 2)}{4x} = \frac{(x - 2)(x + 2)}{2x}
\]
Final answer:
\[
\boxed{\frac{(x - 2)(x + 2)}{2x}}
\]
Geometry and Mensuration
Question Example:
A cylinder has a radius of 7 cm and height of 14 cm. Calculate its total surface area.
Solution:
Surface area of a cylinder:
\[
A = 2\pi r^2 + 2\pi r h
\]
\[
A = 2 \times \pi \times 7^2 + 2 \times \pi \times 7 \times 14
\]
\[
A = 2 \times \pi \times 49 + 2 \times \pi \times 98
\]
\[
A = 98\pi + 196\pi = 294\pi
\]
Using \(\pi \approx 3.142\),
\[
A \approx 294 \times 3.142 \approx 924.588 \text{ cm}^2
\]
Final answer:
\[
\boxed{294\pi \text{ cm}^2 \approx 924.59 \text{ cm}^2}
\]
Trigonometry
Question Example:
In \(\triangle ABC\), \(\angle ABC = 45^\circ\), \(\angle ACB = 60^\circ\). Side \(AB = 10\,cm\). Find side \(AC\).
Solution:
First, find \(\angle BAC\):
\[
\angle BAC = 180^\circ - 45^\circ - 60^\circ = 75^\circ
\]
Using the Law of Sines:
\[
\frac{AB}{\sin C} = \frac{AC}{\sin B}
\]
\[
\frac{10}{\sin 60^\circ} = \frac{AC}{\sin 45^\circ}
\]
Calculate:
\[
\sin 60^\circ \approx 0.866, \quad \sin 45^\circ \approx 0.707
\]
Thus:
\[
AC = \frac{10 \times 0.707}{0.866} \approx \frac{7.07}{0.866} \approx 8.17\,cm
\]
Final answer:
\[
\boxed{AC \approx 8.17\,cm}
\]
Statistics and Probability
Question Example:
A die is rolled twice. What is the probability that both rolls result in a number greater than 3?
Solution:
Possible outcomes for each roll greater than 3: 4, 5, 6 (3 outcomes).
Total outcomes for each roll: 6.
Probability for one roll:
\[
\frac{3}{6} = \frac{1}{2}
\]
For two independent rolls:
\[
P = \frac{1}{2} \times \frac{1}{2} = \frac{1}{4}
\]
Final answer:
\[
\boxed{\frac{1}{4}}
\]

Cons:
- Slightly tricky if students forget the change of base property.
- Could involve more complex log expressions for higher difficulty.
2. Geometry and Mensuration
Sample Question:
A cone has a radius of 3 cm and a height of 4 cm. Calculate its slant height and surface area.
Solution:
- Slant height \( l = \sqrt{r^2 + h^2} = \sqrt{3^2 + 4^2} = \sqrt{9 + 16} = \sqrt{25} = 5\,cm \).
- Surface Area \( SA = \pi r (l + r) = \pi \times 3 \times (5 + 3) = \pi \times 3 \times 8 = 24\pi \,cm^2 \).

3. Trigonometry
Sample Question:
In triangle ABC, angle B is 60°, and side AB = 8 cm. If BC = 10 cm, find the length of AC.
Solution:
Using the Law of Cosines:
\[
AC^2 = AB^2 + BC^2 - 2 \times AB \times BC \times \cos B
\]
\[
AC^2 = 8^2 + 10^2 - 2 \times 8 \times 10 \times \cos 60^\circ
\]
\[
AC^2 = 64 + 100 - 2 \times 8 \times 10 \times 0.5
\]
\[

Solution:
- Mean:
\[
\text{Sum} = 45 + 50 + 55 + 55 + 60 + 65 + 70 + 75 + 80 + 85 = 640
\]
\[
\text{Mean} = \frac{640}{10} = 64
\]
- Median:
Arrange in order (already sorted). Since n=10 (even), median = average of the 5th and 6th terms:
\[
\frac{55 + 60}{2} = \frac{115}{2} = 57.5
\]
Key Takeaways:
- Basic calculations of central tendency.
- Data interpretation skills.
Pros:
- Very straightforward, reinforcing fundamental concepts.
