Question

Two circles with diameters 26 cm and 14 cm touch each other internally. Findthe distance between their centers ​

Answer 1

Answer:

6 cm

Step-by-step explanation:

d=2r

26=2×r

r=13

d=2r

14=2×r

r=7

therefore , 13 - 7= 6cm(since the circles was internally touching)

ans: distance is 6 cm between this two circles .

Hope this answer will help you .

Answer 2

Answer:

The distance between two centers = 6 cm

Step-by-step explanation:

Given data  

Two circles are touch each other internally

Diameter of the circle are

Diameter of the bigger circle d₁ = 26 cm

⇒  radius of the circle r₁ = 26/ 2 = 13 cm

Diameter of the smaller circle d₂ = 14 cm

⇒ radius of the circle r₂ = 14/2 = 7 cm  

here we need to find the distance between their centers

If r₁ and r₂ be the radii of the bigger and smaller circles which are touch each other internally

⇒ the distance between two centers = r₁ - r₂

⇒ the distance between two centers of given circle =  13 - 7 = 6 cm
