What is the area of a rectangle with length 12 cm and width 7 cm?
Answer: 84 cm²
Area = length × width = 12 × 7 = 84 cm².
What is the circumference of a circle with radius 5? (Use π ≈ 3.14)
Answer: 31.4
Circumference = 2πr = 2 × 3.14 × 5 = 31.4.
Two angles are supplementary. If one angle measures 65°, what is the other?
Answer: 115°
Supplementary angles sum to 180°, so 180° - 65° = 115°.
A right triangle has legs of 6 and 8. What is the length of the hypotenuse?
Answer: 10
Using the Pythagorean theorem: √(6² + 8²) = √(36 + 64) = √100 = 10.
What is the volume of a cube with side length 4 cm?
Answer: 64 cm³
Volume = side³ = 4³ = 64 cm³.
What is the sum of interior angles of a triangle?
Answer: 180°
The sum of the interior angles of any triangle is always 180°.
