Eleven Twentieths of the pie are left, so that's 11/20
Method to solve;
Since its given a 1/4 and a 1/5 it's easiest to convert these to twentieths (the lowest common multiple of 4 and 5)
So 1/4= 5/20
1/5 = 4/20
How much is eaten = 5/20 + 4/20 = 9/20
How much remains = Total (20/20) - How much eaten (9/20) = 11/20
The circumference of a circle is 2 times pi times the radius or diameter times pi.
So, in this case, you can multiply 28 with 2 and then multiply it by pi.
(28)(2)(pi)=(56)(pi)=175.84
