Answer:
A. 9A² - 16B²
Step-by-step explanation:
(3A + 4B)(3A - 4B)
Distribute:
3A(3A - 4B)
4B(3A - 4B)
Multiply:
3A(3A - 4B)
3A(3A) + 3A(-4B)
9A² - 12AB
4B(3A - 4B)
4B(3A) + 4B(-4B)
12AB - 16B²
Combine like terms:
9A² - 12AB + 12AB - 16B² <== -12AB + 12AB cancels out
9A² - 16B²
Therefore, our final answer is 9A² - 16B²

It the measure of central angle ABC is π/2 radians ( 90° ) then the shaded sector represents 1/4 of the area of the circle.
Area of the circle:
A = r² π = 6² π = 36 π
A ( ABC ) = 36π : 4 = 6 π
Answer:
6 π units².
