Question

two circle of radius 5.5 cm and 3.3cm respective touch each other what is the distance between their center?​

Answer 1

Answer:

4.4

Explanation:

Radius of circle 1 = 5.5

Circle 2 = 3.3

If they meet each other then they form one other circle of

Diameter 8.8

Then it's center (radius) = 4.4

Answer 2

To Find:-

• The distance between their centre

Given:-

• Radius of two circles are 5.5cm and 3.3 respectively.

Solution:-

→ If the two circles touches each other externally , then the distance between the centres will be equal to the sum of

$\sf{r_1 \: and \: r_2}$

According to the question,

$\sf{5.5cm + 3.3cm }$

$\sf{8.8cm}$

→ And if the two circles touches each other internally , then the distance between the centres will be equal to the difference of

$\sf{r_1 \: and \: r_2}$

According to the question,

$\sf{5.5cm - 3.3cm }$

$\sf{2.2cm}$

Answer:-

The distance between their centre by externally is 8.8cm and the distance between their centre by internally is 2.2cm.
