Question

The diameter of a round skating

rink is 15 m. Find the circumference
of the rink to the nearest meter.

Answer 1

Answer: 47 meters

Explanation:

The equation for the diameter of a circle is
`C=d\pi`, so we just multiply the diameter (15) by
`\pi`.
`15\pi`, or roughly 47.1238898038. Rounded to the nearest meter, 47 meters. Also, happy pi day!
