Answer:
Given that,
Radius of a circle is 3.5 centimetre
To find the circumference and area of the circle.
Step-by-step explanation:
We know that,
Circumference of a circle is,
![2\pi r](https://img.qammunity.org/2023/formulas/mathematics/high-school/lq9ocvc815y81kqkk2foo7l5ja0ltnznvd.png)
where r is the radius of the circle.
Here, r=3.5
Substitute the value of r, we get
![=2*\pi*3.5](https://img.qammunity.org/2023/formulas/mathematics/college/yvxeegy0v1hf8qbz2tjplv0we9zoheer2g.png)
Substitute the value of pi=22/7, we get
![=2*(22)/(7)*3.5](https://img.qammunity.org/2023/formulas/mathematics/college/x9as2ifazjnngnfsggd44admhptwcmlxya.png)
