ICET Mathematical Ability - Geometry 2

Question 1

The diameter of a circle is 14 cm. What is its circumference? (Use π = 22/7)

Accepted Answer

44 cm

Answer

Circumference = πd = (22/7) × 14 = 44 cm.

Question 2

What is the area of a right triangle with legs 6 cm and 8 cm?

Accepted Answer

24 cm²

Answer

Area = (1/2) × base × height = (1/2) × 6 × 8 = 24 cm².

Question 3

In a rhombus, the diagonals are 10 cm and 24 cm. What is the area?

Accepted Answer

120 cm²

Answer

Area = (1/2) × d₁ × d₂ = (1/2) × 10 × 24 = 120 cm².

Question 4

What is the total surface area of a cube with edge length 4 cm?

Accepted Answer

96 cm²

Answer

Total surface area = 6 × side² = 6 × 16 = 96 cm².

Question 5

The exterior angle of a regular polygon is 45°. How many sides does it have?

Accepted Answer

8

Answer

Number of sides = 360° ÷ exterior angle = 360° ÷ 45° = 8.
