Answer:
answer is 7 cm
explanation:
Distance between centre of both circle = 10 cm
Radius of one of the circle (circle1)= 3 cm
Radius of another circle ( circle2) = x cm
As the cicle touch each other externally,
Distance between two centre = Radius of one circle + Radius of another circle
10 cm = 3 cm + x cm
x cm = 10 - 3 cm
x cm = 7 cm
Additional information: diameter of circle 1 is bigger than circle 2 as,
Diameter = Radius x 2
