Q1. The area of a circle with radius 7 cm is: (π = 22/7)
Correct Answer: A
Area = πr² = (22/7) × 7 × 7 = 22 × 7 = 154 cm².
Q2. Find the volume of a cube with side 5 cm.
Correct Answer: C
Volume of cube = a³ = 5³ = 5 × 5 × 5 = 125 cm³.
Q3. The perimeter of a rectangle is 56 cm. If the length is 18 cm, find the breadth.
Correct Answer: B
Perimeter = 2(l+b). 56 = 2(18+b). 28 = 18+b. b = 10 cm.
Q4. A right triangle has legs 6 cm and 8 cm. Find the hypotenuse.
Correct Answer: B
Using Pythagoras: c² = 6² + 8² = 36 + 64 = 100. c = 10 cm. (This is a 6-8-10 = 3-4-5 triple × 2)
Q5. The area of an equilateral triangle with side 4 cm is:
Correct Answer: A
Area = (√3/4) × a² = (√3/4) × 16 = 4√3 cm².
Q6. Volume of a cylinder with radius 7 cm and height 10 cm is:
Correct Answer: B
V = πr²h = (22/7) × 7² × 10 = (22/7) × 49 × 10 = 22 × 7 × 10 = 1540 cm³.
Q7. The diagonal of a square is 10√2 cm. What is its area?
Correct Answer: B
Diagonal of square = a√2. So a√2 = 10√2, a = 10 cm. Area = a² = 100 cm².
Q8. A rhombus has diagonals 12 cm and 16 cm. Find its area.
Correct Answer: C
Area of rhombus = (d1 × d2)/2 = (12 × 16)/2 = 192/2 = 96 cm².
Q9. Total surface area of a sphere with radius 3.5 cm is: (π = 22/7)
Correct Answer: A
TSA = 4πr² = 4 × (22/7) × (3.5)² = 4 × (22/7) × 12.25 = 4 × 38.5 = 154 cm².
Q10. The volume of a cone with radius 6 cm and height 7 cm is: (π = 22/7)
Correct Answer: A
V = (1/3)πr²h = (1/3) × (22/7) × 36 × 7 = (1/3) × 22 × 36 = 22 × 12 = 264 cm³.
