The radius of the fence circle is half its diameter, so is 51.4 feet. The area of a circle is given by the formula ...
A = πr^2
The difference in areas of the two regions is found by subtracting the smaller area from the larger one. So, the difference in area between the fenced area of radius 51.4 feet and the playground area of radius 37.3 feet is ...
∆A = π(51.4^2 -37.3^2) = 1250.67π ≈ 3929 . . . square feet

Difference is subtracting, but you need to have common denominators to do so,.
The LCD for 8 & 12 is 24. Now find equivalent fractions with a denominator of 24.
14 5/8 = 14 15/24
17 5/12 = 17 10/24
17 10/24 - 14 15/24 can't be done since the 10 is smaller. We must borrow from the 17. We will borrow 1 whole, or 24/24.
16 34/24 - 14 15/24 = 2 19/24 B
