Answer:

9,498.5 ft²

Step-by-step explanation:

110 ft = circumference (C)

C=2r

110=2r

110/2=2r/2

55=r

Area of a circle (A) = πr²

Use 3.14 for π

A=3.14(55)²

A=3.14(3025)

A=9,498.5

The area of the garden is 9,498.5 ft²

The total profit is computed as the difference between the revenue and the costs, then the total profit of the kids in this case is:

Profit = $147 - $18 = $129

This means that Tia and Jaden earned $129, if they divide it evenly, each one of them gets $129/2 = $64.5
