Questions & Step-by-Step Solutions
Two circles touch each other externally. If the radius of the first circle is 3 cm and the second is 5 cm, what is the distance between their centers? (2023)
Step 1: Identify the radius of the first circle, which is 3 cm.
Step 2: Identify the radius of the second circle, which is 5 cm.
Step 3: Understand that when two circles touch each other externally, the distance between their centers is equal to the sum of their radii.
Step 4: Add the radius of the first circle (3 cm) to the radius of the second circle (5 cm).
Step 5: Calculate the sum: 3 cm + 5 cm = 8 cm.
Step 6: Conclude that the distance between the centers of the two circles is 8 cm.
