Answer:
10
Step-by-step explanation:
(-1 - 3i)(-1 + 3i) = 1 - 3i + 3i -9i²
1 - 9i²; i² = -1, therefore 1 - 9(-1) = 1 + 9 = 10
Answer:
1 2/3
Step-by-step explanation:
well first reduce it which would be 5/3 since the greatest common denominator would be 4. Then put 3 in the 5 which goes only once and 2 is left over. Keep the threeas the denominator instead of the numerator.
Area of circle = πr²
1075.21 = πr²
1075.21/π = r²
r = √1075.21/π
r = 18.5
I believe it would be 130 degrees
