Q2. What is π?
- The ratio of a circle’s circumference to its diameter, the same for all circles
- Exactly 22/7
- Exactly 3.14
- The area of a unit circle in square cm only
Show answer
Answer: A. The ratio of a circle’s circumference to its diameter, the same for all circles
Why: π is irrational; 22/7 is only an approximation. [p.120–124]
Why: π is irrational; 22/7 is only an approximation. [p.120–124]
Q3. The circumference of a circle is 44 cm. What is its radius (cm)? (Use π = 22/7.)
Show answer
Answer: 7 (± 0)
Why: 2 × 22/7 × r = 44 → r = 7. [p.129]
Why: 2 × 22/7 × r = 44 → r = 7. [p.129]
Q4. Find the circumference of a circle of radius 7 cm (π = 22/7).
Show answer
Answer: 44 (± 0)
Why: 2 × 22/7 × 7 = 44 cm. [p.129]
Why: 2 × 22/7 × 7 = 44 cm. [p.129]
Q5. A car tyre has diameter 56 cm. How far does the car move in one revolution (cm, π = 22/7)?
Show answer
Answer: 176 (± 0)
Why: πd = 22/7 × 56 = 176 cm. [p.130]
Why: πd = 22/7 × 56 = 176 cm. [p.130]
