B) 4in
C)5.73 in
D)5 in
E)8.5 in

Answer 1

Answer:

the answer is c

Step-by-step explanation:

you work backwards so divide it by pi so 3.14 in this case and then you have the diameter

Answer 2

Answer:

C

Step-by-step explanation:

Circumference can be found using

c=$\pi$d

We know the circumference is 18, so we can substitute it in

18=$\pi$d

We want to find d, so we have to isolate it.

To do this, divide both sides by pi

d=5.72957795131

Rounded to the nearest hundreth

d=5.73

Diameter is 5.73 inches, or choice C
