How do you estimate the circumference of a circle when you know the diameter?

The circumference of a circle is given by π × diameter. π =3.14159265...... It is approximately 3.14 which, itself, is approximately 22/7. To estimate the circumference of a circle, multiply the diameter by 3 and add the diameter divided by 10 and that division divided by 2; this will give you 3.15 × diameter which is fairly close. Alternatively, multiply the diameter by 22 and divide by 7.
