circumference = 2πr = 2 * 3.14 * 1.6 =10.048=10.05inch
Answer:
radius is approximately 1.6 inches
circumference is approximately 10.05 inches
Step-by-step explanation:
radius formula: d ÷ 2
d = 3.2 ÷ 2
= 1.6
circumference formula: pi × 2 × r
pi = 3.14
r = 1.6
3.14 × 2 × 1.6 = 10.048
round to nearest hundredth = 10.05
