1. The answer is 50.24
Explanation:
The formula to find the circumference is 2πr. This means 2 times π times radius. π is the sign for pi, which equals=3.14
You have the diameter of 14cm.
Radius is half of the diameter so your radius is 8.
This means your formula is 2•π•8.
2•π•8 equals 50.24
2. The answer is 37.68
Step-by-step explanation:
You are given the radius of 6mm. Since you already have the radius that means your formula is
2•π•6
This gives you 37.68.
Hope this helps.
