Question

Two circles of radii 5.5 cm and 3.3 cm respectively, touch each other externally. Then the distance between their centres is ______.

विकल्प

• 4.4 cm

• 8.8 cm

• 2.2 cm

• 8.3 cm

Answer 1

Two circles of radii 5.5 cm and 3.3 cm respectively, touch each other externally. Then the distance between their centres is 8.8 cm.

Explanation:

Given:

• Radius of first circle r₁ = 5.5 
• Radius of second circle r₂ = 3.3 
• The circles touch each other externally

Distance = r₁ ​+ r_2​

Distance = 5.5 + 3.3

 Distance = 8.8 cm
