Questions & Step-by-Step Solutions

In a circle, if the diameter is 10 cm, what is the length of the radius?
  • Step 1: Understand that a circle has a diameter and a radius.
  • Step 2: Know that the diameter is the distance across the circle through the center.
  • Step 3: Remember that the radius is the distance from the center of the circle to the edge.
  • Step 4: Realize that the radius is always half of the diameter.
  • Step 5: Since the diameter is given as 10 cm, divide it by 2 to find the radius.
  • Step 6: Calculate 10 cm / 2 = 5 cm.
  • Step 7: Conclude that the radius of the circle is 5 cm.
