Hello!
<h2>Answer:</h2>We'll start by calculating the areas of Kylie and Paige's circles.
Kylie's Circle:
A = πr²
Since we need the radius for the formula, we must divide the diameter in half to get it.
r = d ÷ 2
r = 8 ÷ 2
r = 4
Now, let's substitute our values into the formula.
A = 3.14 × 4²
A = 3.14 × 16
A = 50.24 cm²
Paige's Circle:
A = πr²
A = 3.14 × 3²
A = 3.14 × 9
A = 28.26 cm²
We can round both of these areas to the nearest whole number. Then, we must subtract Paige's circle area by Kylie's.
50 - 28 = 22
