Answer for (a) to (e) = 0.32

Calculate the ratio to the nearest hundredth.

Find the Ratio of Diameter (d) and circumference (C)

Step by step explanation:

In order to determine the ratio we must know the formula for the circumference of a circle. Then relate it to the diameter.

But since we have been the value if both circumference and diameter, we would just calculate the ratio.

Circumference of a circle = 2πr

Where d = diameter = 2r

Circumference = πd

a) d = 20 in.

C = 62.83 in.

Ratio of Diameter (d) and circumference (C) = d:C

= 20/(62.83)

d:C = 0.32

b) d=10 in.

C =31.41 in.

d:C = 10/(31.41)

d:C = 0.32

c) d =6 in.

C =18.84 in.

d:C = 6/(18.84)

d:C = 0.32

d) d= 2 in.

C = 6.28 in.

d:C = 2/6.28

d:C = 0.32

e) d = 1 in.

C = 3.14 in.

d:C = 1/3.14

d:C = 0.32

The above answers indicate that the ratio of a circumference of a circle to its diameter = d/C = d/(π×d)

= 1/π = 0.32
