Answer:
A ≈ 35.3 units²
Step-by-step explanation:
Calculate the radius CB using Pythagoras' identity in the right triangle.
CB² + AB² = AC²
CB² + 6² = 9²
CB² + 36 = 81 ( subtract 36 from both sides )
CB² = 45 = r²
Then area of quarter circle is
A = × πr² =
× π × 45 ≈ 35.3
Here you divide the number from denominator to numerator. Example 3/3=1, 8/2=4 in denominator and 1 in numerator since 2/2=1
