Let Julie’s age be x years, then Janet=x+3, brother=x-8.
x+x+3+x-8=55, 3x-5=55, 3x=60, x=20.
The ages are Julie is 20, Janet is 23 and their brother is 12.

To find this answer, you would need to use the equation for area of a circle, or in this case, a=3.14x289, since 3.14 is pi and 289 is your radius squared. giving you a final answer of 907.46 feet squared.
