the circumference of a circular painting is 53.38 feet. what is the diameter of the painting? use 3.14 π and do not round your answer

Answer 1

53.38= 2pi(r) = 2(3.14)r

r = 53.38/6.28 =

diameter = 2r = 53.38/3.14 = 17 feet. That's not rounded. If you round pi to 2 decimals, then it comes out an even 17

diameter= circumference/pi

if you use a closer approximation for pi = 3.14159 then diameter = 16.99139...
