Answer:
9.42 units (3 s.f.)
Step-by-step explanation:
Circumference of circle= 2πr
Radius
= diameter ÷2
= 3 ÷2
= 1.5
Circumference of circle
= 2(π)(1.5)
= 3π
= 9.42 units (3 s.f.)
Answer:
C=3π OR around 9.42478...
Step-by-step explanation:
If the diameter is 3, then the radius is 1.5
C=2πr
C=2π(1.5)
C=3π [You can also see that you could find the circumference by multiplying the diameter to pi because 2r is diameter.]
C= roughly 9.42478...
