Answer:
14.6mm
Explanation:
The formula for finding the circumference of a circle is 2πr.
The circumference is 91.688 millimeters inorder to find the radius we have to do the opposite or inverse of multiplication which is division.
So we divide the circumference by 2 and pi which is 3.14 which will give us the radius
r = radius = 91.668 ÷ 3.14 ÷ 2 = 14.6
