What is the circumference of a circle with a diameter of 10 cm? (Use π ≈ 3.14)
Answer: 31.4 cm
Circumference = π × diameter = 3.14 × 10 = 31.4 cm.
Two angles are supplementary. If one angle measures 65°, what is the measure of the other angle?
Answer: 115°
Supplementary angles sum to 180°, so the other angle = 180° − 65° = 115°.
A triangle has sides of length 5, 12, and 13. What type of triangle is this?
Answer: Right triangle
Since 5² + 12² = 25 + 144 = 169 = 13², the Pythagorean theorem is satisfied, making it a right triangle.
What is the area of a triangle with a base of 8 meters and a height of 5 meters?
Answer: 20 m²
Area of a triangle = ½ × base × height = ½ × 8 × 5 = 20 m².
How many degrees are in a complete rotation (full circle)?
Answer: 360°
A full rotation around a central point equals 360 degrees.
A rectangular room is 15 feet long and 10 feet wide. What is its area?
Answer: 150 sq ft
Area = length × width = 15 × 10 = 150 square feet.
