Question 1 · 1 mark · Difficulty 1/3

A circle has a radius of 8 cm. Calculate its area. Give your answer in terms of π.

  1. 16π cm²
  2. 64π cm²
  3. 8π cm²
  4. 32π cm²
Show answer & explanation
✓ Answer: B64π cm²
Area = πr² = π × 8² = 64π cm². A common mistake is to use A = πd², which would give 256π, or to forget to square the radius and write 8π.
Question 2 · 1 mark · Difficulty 1/3

What is the formula for the circumference of a circle with diameter d?

  1. C = πr²
  2. C = 2πr²
  3. C = πd
  4. C = πd²
Show answer & explanation
✓ Answer: CC = πd
The circumference of a circle is found using C = πd, where d is the diameter. Alternatively, since d = 2r, this can be written as C = 2πr. The formula C = πr² gives the area, not the circumference.
