Two circles have radii of 3 cm and 5 cm. What is the distance between their centers if they are externally tangent?

Two circles have radii of 3 cm and 5 cm. What is the distance between their centers if they are externally tangent?

Step 1: Identify the radii of the two circles. The first circle has a radius of 3 cm and the second circle has a radius of 5 cm.
Step 2: Understand that when two circles are externally tangent, the distance between their centers is equal to the sum of their radii.
Step 3: Add the two radii together: 3 cm (radius of the first circle) + 5 cm (radius of the second circle).
Step 4: Calculate the sum: 3 + 5 = 8 cm.
Step 5: Conclude that the distance between the centers of the two circles is 8 cm.
