The circumference of the vinyl record is 62.8cm. This is calculated using the circumference formula; C = ?D, where C is the circumference, ? the pie value which is 3.14 and D the diameter. Therefore, C= 3.14 ? 20 = 62.8cm.

You do the diameter x pie to get your circumference .Pie is 3.14 .So 3.14x20 will give you your circumference .
