The diameter of a circle is 14 cm. What is its circumference? (Use π = 22/7)
Answer: 44 cm
Circumference = πd = (22/7) × 14 = 44 cm.
What is the area of a right triangle with legs 6 cm and 8 cm?
Answer: 24 cm²
Area = (1/2) × base × height = (1/2) × 6 × 8 = 24 cm².
In a rhombus, the diagonals are 10 cm and 24 cm. What is the area?
Answer: 120 cm²
Area = (1/2) × d₁ × d₂ = (1/2) × 10 × 24 = 120 cm².
What is the total surface area of a cube with edge length 4 cm?
Answer: 96 cm²
Total surface area = 6 × side² = 6 × 16 = 96 cm².
The exterior angle of a regular polygon is 45°. How many sides does it have?
Answer: 8
Number of sides = 360° ÷ exterior angle = 360° ÷ 45° = 8.
If the side of a square is increased by 20%, by what percentage does its area increase?
Answer: 44%
New area = (1.2s)² = 1.44s², so area increases by 44%.
