To the nearest tenth of a centimeter, what is the circumference of a circle with a radius of 2.5 cm? (Use 3.14 for π.) a. 25.1 cm c. 15.7 cm b. 38.7 cm d. 12.9 cm
The circumfrence of a circle is [tex] \pi d[/tex] diamter is 2r ( Two times the radius ) So you would now have [tex]5 \pi [/tex] \pi = 3.14 so (3.14)(5) = 15.7 The answer is B, 15.7 In you question you wrote it as C
