Question

Find the circumference of the circle. use 3.14 for the 3.14 symbol and round to the nearest hundredth
one side of the circle is 20ft and the other side is unknown

Answer 1

I’m not sure whether the 20 ft is the circle’s radius or its diameter. Which one did you mean?

Here are both possibilities (using π = 3.14 and rounding to the nearest hundredth):

- If 20 ft is the diameter:
C = π·d = 3.14 × 20 = 62.8 → 62.80 ft

- If 20 ft is the radius:
C = 2·π·r = 2 × 3.14 × 20 = 125.6 → 125.60 ft

Tell me which one applies and I’ll confirm.
