Sample Problems and Solutions from the Answer Key
Providing example problems and solutions can give insights into the types of questions found on the exam and how the answer key addresses them.
Example 1: Finding the Length of a Diagonal in a Rectangle
Problem: A rectangle has a length of 8 cm and a width of 6 cm. Find the length of its diagonal.
Solution:
Using the Pythagorean theorem:
\( d = \sqrt{(8)^2 + (6)^2} = \sqrt{64 + 36} = \sqrt{100} = 10\, \text{cm} \)
Answer: 10 cm

Example 2: Calculating the Area of a Sector
Problem: In a circle with a radius of 10 meters, find the area of a sector with a central angle of 60°.
Solution:
Sector area formula:
\( \text{Area} = \frac{\theta}{360} \times \pi r^2 \)
Plugging in the values:
\( \text{Area} = \frac{60}{360} \times \pi \times 10^2 = \frac{1}{6} \times \pi \times 100 = \frac{100}{6} \pi \approx 52.36\, \text{m}^2 \)
Answer: Approximately 52.36 square meters
