Question

Why might the measured radii and circumferences not be exactly proportional?

Answer 1

$\huge{\mathbb{\purple{ A{\pink{N{\green{S[\blue{W{\red{ E{\orange{R}}}}}}}}}}}}]$

If we write for the circumference of a circle, this proportional relationship can be written . The area of a circle with radius is approximately . Unlike the circumference, the area is not proportional to the radius because cannot be written in the form for a number .

Answer 2

we write for the circumference of a circle, this proportional relationship can be written . The area of a circle with radius is approximately . Unlike the circumference, the area is not proportional to the radius because cannot be written in the form for a number .
