Questions & Step-by-Step Solutions

What is the length of the diameter of a circle with radius 7?
  • Step 1: Understand that the diameter of a circle is the distance across the circle through its center.
  • Step 2: Know that the radius is the distance from the center of the circle to the edge.
  • Step 3: Remember that the diameter is always twice the length of the radius.
  • Step 4: Since the radius is given as 7, we can calculate the diameter by multiplying the radius by 2.
  • Step 5: Perform the calculation: 2 * 7 = 14.
  • Step 6: Conclude that the length of the diameter is 14.
