Question

Find the exact circumference of a circle with the given radius 5” c=?

Answer 1

C = 31.42

Explanation:

radius = 5

C = 2 π r

C = 2 · π · 5

C = 31.41593

then you round so it equals 31.42 instead

Answer 2

Answer: 10pi

Explanation:

C=2*pi*r

C=2*pi*5

C=10*pi (exact)

This is exact if u want numbers, you’ll have to round-off and you can just put 10xpi into a calculator If u want to see.
