alleryA circular track has a radius of 7 cm. What is its circumference? (Take π = 22/7)
- 44 cm
- 22 cm
- 154 cm
- 88 cm
Show answer and solution
Correct answer: A. 44 cm
Circumference is 2πr, so 2 × 22/7 × 7 gives 44 cm.

Worked practice questions
Find the area enclosed by a circle of radius 14 cm. (Take π = 22/7)
- 616 cm²
- 1232 cm²
- 308 cm²
- 88 cm²
Show answer and solution
Correct answer: A. 616 cm²
Area is πr², so 22/7 × 14 × 14 gives 616 cm².
A wire bent into a circle has length 88 cm. What is the radius of that circle? (Take π = 22/7)
- 14 cm
- 28 cm
- 44 cm
- 7 cm
Show answer and solution
Correct answer: A. 14 cm
From 2πr = 88, r = 88 × 7 / 44 = 14 cm.
