Step-by-step explanation:
Area of circle:
By using the area of a circle, we can get the area of a semicircle:
Let's convert the mixed fraction to an improper fraction and then a decimal:
= 
= 
Now, we solved for the diameter, to get the radius, we need to divide the diameter by 2:
Now we have the radius, so we can plug in our values and find the area:
Answer:
x⁴ + 3x³ - 5x + 1
Step-by-step explanation:
(x - 1)(x³ + 4x² + 4x - 1)
Same as writing....
x(x³ + 4x² + 4x - 1) - 1(x³ + 4x² + 4x - 1)
x⁴ + 4x³ + 4x² - x - x³ - 4x²- 4x + 1
x⁴ + 3x³ - 5x + 1
