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
Answer:
we can get 3/2 as the answer
For the complex roots I got 1,2,-3
23/5, 5/2, 31/9, and 19/7
All you have to do is multiply the whole number by the denominator and add the numerator. For example:
5 3/6 5*6 is 30 +6 is 36
therefore the improper fraction is 36/6
Set it up as a propotion and cross multiply. 10/23=15/x answer is 34.5
