The length of the fencing corresponds to the length of the perimeter of the garden:

We also know that the perimeter of a circle is given by:

where r is the radius of the circle.
Putting together the two equations, we have

from which we can find r, the radius of the garden:

Answer:
Given:
Cost of doughnut at one shop = £1.40
Unknown:
Difference in the cost of doughnuts at the two shops = ?
To find the difference in the cost of doughnuts at the two shops, we must know the cost of doughnut at the second shop;
Given that the cost of doughnut at the other shop is 20% more;
= 1.20 x £1.4
= £1.68
The difference in the cost of doughnuts = £1.68 - £1.40 = £0.28
So the answer is £0.28
