What is the area of a triangle with a base of 10 cm and a height of 6 cm?
Answer: 30 cm²
The area of a triangle is (1/2) × base × height = (1/2) × 10 × 6 = 30 cm².
What is the circumference of a circle with a radius of 7 units? (Use π ≈ 3.14)
Answer: 43.96 units
Circumference = 2πr = 2 × 3.14 × 7 = 43.96 units.
A rectangle has a length of 12 m and a width of 5 m. What is its perimeter?
Answer: 34 m
Perimeter = 2(length + width) = 2(12 + 5) = 34 m.
Which of the following correctly describes complementary angles?
Answer: Two angles that sum to 90°
Complementary angles are two angles whose measures add up to exactly 90°.
What is the volume of a rectangular prism with length 4, width 3, and height 5?
Answer: 60 cubic units
Volume = length × width × height = 4 × 3 × 5 = 60 cubic units.
A line segment goes from point (2, 3) to point (6, 3). What is its length?
Answer: 4 units
Since both points share y = 3, the length is the difference in x-coordinates: 6 − 2 = 4 units.
