A square has a perimeter of 48 cm. What is its area?
Answer: 144 cm²
Each side = 48 ÷ 4 = 12 cm; Area = 12² = 144 cm².
In coordinate geometry, what is the midpoint of the segment connecting (−4, 2) and (6, −8)?
Answer: (1, −3)
Midpoint = ((−4+6)/2, (2+(−8))/2) = (2/2, −6/2) = (1, −3).
A cone has a radius of 4 cm and a height of 9 cm. What is its volume? (Use π ≈ 3.14)
Answer: 150.72 cm³
Volume of a cone = (1/3)πr²h = (1/3)(3.14)(16)(9) = (1/3)(452.16) = 150.72 cm³.
An angle measures 128°. What is the measure of its complement?
Answer: Complementary angles cannot be formed
Complementary angles must sum to 90°, but 128° > 90°, so no complement exists.
A map has a scale of 2 cm : 50 km. Two cities are 7 cm apart on the map. What is the actual distance between them?
Answer: 175 km
Each cm represents 25 km, so 7 cm × 25 km/cm = 175 km.
Which of the following figures has exactly one pair of parallel sides?
Answer: Trapezoid
A trapezoid has exactly one pair of parallel sides, unlike parallelograms which have two pairs.
A right angle is bisected. What is the measure of each resulting angle?
Answer: 45°
A right angle measures 90°; bisecting it creates two equal angles of 90° ÷ 2 = 45° each.
