Two circles having radii 3.5cm and 4.8 cm tauch each other internally find the distance between their antres
Answers
Step-by-step explanation:
Given:
The radius of two circles is 3.5 cm and 4.8 cm.
To find:
The distance between the centers of the circles touching each other internally is equal to the difference of their radii.
Step 1:
It is known that the distance between the centers of the circles touching each other internally is equal to the difference of their radii.
Distance = 4.8 - 3.5
Simplifying,
Distance = 1.3 cm
Therefore, the distance between their centers is = 1.3 cm
Final Answer
The distance between the centers of the circles touching each other internally is 1.3 cm.
tip =
The distance between the centers of the circles touching each other internally is equal to the difference in their radii.

Answer:
A
r= 4.8
πr2
3.14*4.8*4.8
3.14*23.04
72.34
B
r = 3.5
πr2
3.14*3.5*3.5
3.14*12.25
38.46
A-B
72.34 - 38.46
= 33.87
