The formula for finding the circumference is pi times the diameter so If your giving it in terms of pi then you're just finding the diameter which is 15
The answer is £140
First you find 20% of 1200 (which is basically 20 times 12) which gives you £240.
You add £240 to £1200 which is £1440
Then you take £300 off £1440 since he already paid the deposit.
That leaves you with £1140
1140 divided by 10 is 114
