Answer:
2. 19.47 in
3. 153.86 square centimeters
Explanation:
2. The circumference of a circle is π times the diameter, so in this case it is 6.2 * 3.14 = 19.47 in (rounding to nearest hunderdth).
3. The area of a circle is π/4 times the diameter squared, so in this case it is 14^2 * 3.14 / 4 = 153.86 square centimeters.
