Question: If a circle has a radius of 5 cm, what is the circumference of the circle?

Options:

  1. 10π cm
  2. 15π cm
  3. 20π cm
  4. 25π cm

Correct Answer: 10π cm

Solution: 

The circumference of a circle is given by the formula C = 2πr. Thus, C = 2π(5) = 10π cm.

Questions & Step-by-Step Solutions

If a circle has a radius of 5 cm, what is the circumference of the circle?
  • Step 1: Identify the radius of the circle. In this case, the radius (r) is 5 cm.
  • Step 2: Recall the formula for the circumference of a circle, which is C = 2πr.
  • Step 3: Substitute the radius into the formula. So, C = 2π(5).
  • Step 4: Calculate the multiplication. 2 times 5 equals 10, so C = 10π cm.
  • Step 5: Write the final answer. The circumference of the circle is 10π cm.
  • Circumference of a Circle – The circumference is the distance around the circle, calculated using the formula C = 2πr, where r is the radius.
