Questions & Step-by-Step Solutions

If a circle has a radius of 5 cm, what is its circumference?
  • Step 1: Understand that the circumference of a circle is calculated using the formula: Circumference = 2πr.
  • Step 2: Identify the radius of the circle, which is given as 5 cm.
  • Step 3: Substitute the radius (r) into the formula: Circumference = 2π(5).
  • Step 4: Calculate 2 times 5, which equals 10.
  • Step 5: Now, multiply 10 by π to get the final circumference: Circumference = 10π cm.
  • Circumference of a Circle – The circumference of a circle is calculated using the formula C = 2πr, where r is the radius.
