Step-by-step explanation:
its .86 which is closer to .87
so choose the first one
The area of a whole circle is (pi) (radius²) .
So the area of half of it would be <em>(1/2) (pi) (radius²) .</em>
If you don't know the radius, then you can use the formula
Area = (1/8) (pi) (diameter²) .
Answer:
0.55 would be the decimal form

Answer:
(3x + 2)(x-4)
Step-by-step explanation:
3x² - 10x - 8 = 0
(splitting the middle term)
3x² -12x + 2x -8 = 0
3x(x-4) + 2(x-4) = 0
(3x + 2)(x-4) = 0
(3x + 2)(x-4) is the correct answer (option a)
