Worked practice questions

The distance all the way round a circle is called its:

  1. Circumference
  2. Circumstance
  3. Circumvention
  4. Circumscription
Show answer and solution

Correct answer: A. Circumference

1. A circle has no straight sides to add. 2. The distance round it gets a special name. 3. That name is the circumference. _Source: syllabus Mathematics Class X, Chapter 12, Areas Related to Circles._

The ratio of a circle's circumference to its diameter is denoted by the letter:

  1. Rho
  2. Pi
  3. Phi
  4. Psi
Show answer and solution

Correct answer: B. Pi

1. This ratio is the same for every circle. 2. A Greek letter is used for it. 3. That letter is pi. _Source: syllabus Mathematics Class X, Chapter 12, Areas Related to Circles._

The circumference of a circle equals pi multiplied by the:

  1. Diameter
  2. Perimeter
  3. Parameter
  4. Millimetre
Show answer and solution

Correct answer: A. Diameter

1. Pi is defined as circumference over diameter. 2. Rearranging gives circumference as pi times diameter. 3. So it is the diameter. _Source: syllabus Mathematics Class X, Chapter 12, Areas Related to Circles._
