If two circles touch each other externally. The radios of circle A is 2 cm and radios of circle 8 is 3 cm. Distance between the centers of A & B will be:
Answer: 5 cm
Explanation
To find the distance between the centres of two externally touching circles, we can use the fact that the distance between the centres is equal to the sum of the radii of the two circles.
Let's denote the radius of circle A as rA (which is 2 cm) and the radius of circle B as rB (which is 3 cm).
The distance between the centres of the two circles, d, can be calculated as:
d = rA + rB
Plugging in the values:
d = 2 cm + 3 cm
d = 5 cm
Therefore, the distance between the centres of Circle A and Circle B is 5 cm.
