Use 3.14 for π and enter your answer as a decimal.
units

Answer 1

Answer:

d = 0.999 units to 3 d.p.

Step-by-step explanation:

Circumference of a circle is given by the formula

C = 2πr  Or  C = πd

Since we need the diameter we need to use the second formula :

3.14 units = π×d

Divide both sides by π :

(3.14 ÷ π ) units = d

d = 0.999 units to 3 d.p.

Hope this helped and have a good day

Answer 2

Answer:

The diameter is 1 unit

Step-by-step explanation:

The circumference is found by

C = pi * d  where d is the diameter

3.14 = 3.14 * d

Divide each side by 3.14

3.14 / 3.14 = 3/14 d / 3.14

1 = d

The diameter is 1 unit
