What is the area of a circle with a diameter of 10 units? (Use π ≈ 3.14)
Answer: 78.5 square units
Radius = 5; Area = πr² = 3.14 × 25 = 78.5 square units.
Two parallel lines are cut by a transversal. Which pair of angles are always equal?
Answer: Corresponding angles
When a transversal crosses parallel lines, corresponding angles are always congruent (equal in measure).
What is the length of the hypotenuse of a right triangle with legs of 3 and 4?
Answer: 5
Using the Pythagorean theorem: c = √(3² + 4²) = √(9 + 16) = √25 = 5.
How many degrees are in the sum of interior angles of a quadrilateral?
Answer: 360°
The sum of interior angles of any quadrilateral is always 360°.
What is the slope of a line that passes through points (1, 2) and (3, 8)?
Answer: 3
Slope = (8 − 2) / (3 − 1) = 6 / 2 = 3.
A square has a perimeter of 36 cm. What is its area?
Answer: 81 cm²
Side = 36 ÷ 4 = 9 cm; Area = 9² = 81 cm².
