the circumference of a circle is 11.4mm. find the length of the diameter. give your answer rounded to 3SF.

3.627 = d

Step-by-step explanation:

C = 11.4mm

d = ?

C = πd

11.4 = 22/7 * d

cross multiply

11.4 * 7 = 22d

79.8 = 22d

Divide both sides of the equation b 22

79.8/22 = 22d/22

3.627 = d
