Tho circles of denter \( P \) and \( Q \) with radis 4 en and 5.5 cm louches exlernally what is the dislance between their centers? 4 cm 5.5 cm 9.5 1.5

To find the distance between the centers of two circles that touch externally, you can simply add their radii together. Given: - Radius of circle \( P \) = 4 cm - Radius of circle \( Q \) = 5.5 cm The distance \( d \) between the centers of the circles is given by: \[ d = \text{Radius of } P + \text{Radius of } Q \] Calculating this: \[ d = 4 \, \text{cm} + 5.5 \, \text{cm} = 9.5 \, \text{cm} \] So, the distance between the centers of the circles is **9.5 cm**.
