What is a circumference of a smaller circle the raduis of a smaller circle 3inch and the the raduis of a larger is circle is 7so,what is approximate circumference of a smaller circle

Answer 1

18.85 inches.

Explanation:

We have been given that the radius of a smaller circle 3 inch. We are asked to find the circumference of smaller circle.

We know that circumference of a circle is equal to
`2\pi r`, where r represents radius of circle.

`\text{Circumference of smaller circle}=2\pi (3\text{ inches})`

`\text{Circumference of smaller circle}=6\pi\text{ inches}`

`\text{Circumference of smaller circle}=18.84955592\text{ inches}`

`\text{Circumference of smaller circle}\approx 18.85\text{ inches}`

Therefore, the circumference of smaller circle is approximately 18.85 inches.
