Question

The radius of a circle is 30 feet. What is the circumference of the circle? Use 3.14 for pi

Answer 1

Answer:

C≈188.5ft

C=2πr=2·π·30≈188.49556ft

Step-by-step explanation:

If we want the exact circumference or area of a circle, we leave the symbol π in the answer. We can get an approximate answer by substituting 3.14 as the value of π . We use the symbol ≈ to show that the result is approximate, not exact.
