Answer:
18.85 inches.
Step-by-step 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
, where r represents radius of circle.
![\text{Circumference of smaller circle}=2\pi (3\text{ inches})](https://tex.z-dn.net/?f=%5Ctext%7BCircumference%20of%20smaller%20circle%7D%3D2%5Cpi%20%283%5Ctext%7B%20inches%7D%29)
![\text{Circumference of smaller circle}=6\pi\text{ inches}](https://tex.z-dn.net/?f=%5Ctext%7BCircumference%20of%20smaller%20circle%7D%3D6%5Cpi%5Ctext%7B%20inches%7D)
![\text{Circumference of smaller circle}=18.84955592\text{ inches}](https://tex.z-dn.net/?f=%5Ctext%7BCircumference%20of%20smaller%20circle%7D%3D18.84955592%5Ctext%7B%20inches%7D)
![\text{Circumference of smaller circle}\approx 18.85\text{ inches}](https://tex.z-dn.net/?f=%5Ctext%7BCircumference%20of%20smaller%20circle%7D%5Capprox%2018.85%5Ctext%7B%20inches%7D)
Therefore, the circumference of smaller circle is approximately 18.85 inches.
Answer:
x=1/2
Step-by-step explanation:
Set up the equation: 2x-1=0
Add one to both sides. 2x=1
Divide two by both sides: x=1/2
Therefore, x =1/2, or .5
