Answer:
Step-by-step explanation:
CIRCUMFERENCE AND AREA OF CIRCLES 1/16 INCH TO 8 7/8 INCHES
Diameter in Inches Circumference in
2-3/4 8-5/8 .3275
2-7/8 9 .3382
3 9-3/8 .3491
Answer: 9.42478
2π·r² would be the correct formula to use. just plug in the numbers. half of 3 is 1.5 since the radius is half of the diameter and the (2·3.14)·1.5² just put that in a calculator and then you get your answer.
