Question

A circle has a circumference of 50.24 units.what is the radius of the circle?

Answer 1

R=8 when pi is 3.14 when it's not rounded it would be 50.24 I think

Answer 2

Answer:

r=8 (when pi is rounded to 3.14), and r = 50.24/(2*pi) when pi isn't rounded

Step-by-step explanation:

I'm guessing that they rounded pi to 3.14, so I will do the problem like that is the case...(but I will include an answer if they didn't)...the circufrence of a circle is 2*pi*r, so 2*pi*r=50.24. When you divide both sides by 3.14, you get 2r=16, meaning r=8. Without rounding, r would actually be 50.24/(2*pi)
