What is the surface area of a cube with side length 4 cm?
Answer: 96 cm²
Surface area of a cube = 6s² = 6 × 16 = 96 cm².
Two supplementary angles are in a ratio of 2:3. What is the measure of the larger angle?
Answer: 108°
Supplementary angles sum to 180°; the larger is (3/5) × 180 = 108°.
A line segment has endpoints at (1, 2) and (5, 6). What is its length?
Answer: 5.66
Distance = √((5−1)² + (6−2)²) = √(16 + 16) = √32 ≈ 5.66.
Which transformation preserves both shape and size of a figure?
Answer: Reflection
A reflection is a rigid transformation (isometry) that preserves shape and size.
The volume of a cylinder with radius 3 in and height 7 in is approximately: (Use π ≈ 3.14)
Answer: 197.8 in³
V = πr²h = 3.14 × 3² × 7 = 3.14 × 9 × 7 ≈ 197.8 in³.
Which of the following is NOT a property of a rhombus?
Answer: All angles are right angles
A rhombus does not require right angles; a square is the special rhombus with right angles.
If two triangles are similar, their corresponding sides are:
Answer: Proportional
Similar triangles have the same shape but not necessarily the same size, so sides are proportional.
